Structural and optical parameters of SZO sputtered grown film were determined by ellipsometry and field emission scanning electron microscopy (FE-SEM), and I-V analysis of the SZO/n-Si heterojunction device in dark. A smooth film without any grain boundaries is observed in SEM analysis. The bandgap (Eg) of the grown SZO film is obtained and the value of Eg obtained is 3.92 eV. A high refractive index in the range of n=1.85-2.08 is shown by the deposited SZO film in the ultraviolet (UV)-visible region, moreover, it can be seen from the ellipsometry analysis that the fundamental absorption edge is obtained near the UV region. A rectification ratio of ~ 16 times is observed at ±4 V for SZO/n-Si heterojunction. The Study concludes that SZO material has the potential to be used in the application dealing with the UV region of the light spectra.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"25 1","pages":"474-477"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90498168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TM-GQDs with five metals (Cr, Mo, W, Pd, and Pt) and pristine GQDs were investigated to explore the possibility of engineering the optical characteristics. By Density Functional Theory and Time-Dependent Density Functional Theory, excited energy states and absorption spectra were analyzed. As a function of graphene quantum dot sizes and TMs, significant changes in HOMO-LUMO levels and optical transition energies were observed. The HOMO-LUMO gaps and energy levels in the visible range clearly indicate the adatom induced energy level shifts, showing smaller energy gaps in TM-GQDs than the pristine GQDs. The calculated THz absorption spectra show strong dependency on the size and adatom mass of TM-GQDs. The tunable optical properties of the TM-GQDs can be utilized as optical sources for future display applications.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"37 1","pages":"130-133"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82864302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing a three enzyme cascade of amylase, maltase, and glucokinase we found a ~3-fold enhancement in product formation when all three enzymes were bound to the same NP as compared to controls. This strongly suggests that the increased kinetics was due to substrate channeling. Additional controls were realized to ensure that only when the enzymes were bound to the NPs was enhancement observed by modifying the ratio of enzyme to NP. Furthermore the experiments support a model where a single-layer of enzymes conjugate to the NPs independently of the enzyme to NP ratio. Being able to conjugate entire cascades on individual NPs should allow for optimized design of NPs and enzyme cascades for in vitro biocatalysis.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"39 1","pages":"393-396"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81460513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a dimer formed by two nanoparticles with unequal doping levels, the intrinsic resonances of the nanoparticles are carried over to the coupled configuration of the dimer, giving rise to two resonances, slightly shifted from those of the intrinsic particles. An important characteristic of the enhanced field in the gap is the intensity profile swaying when the frequency of the applied field is varied from one resonance to the other. In this work, the field distribution in an asymmetric semiconductor nanodimer is computed by numerical simulation of the charge-field interaction in the semiconductor, employing a transport formulation for charge dynamics. Charge distribution in the semiconductor, field intensity in the gap and the collective response in terms of the total dipole moment are obtained. Interpretation of the results is presented in light of polarization coupling and interference effects between the particles. Potential application of the dynamical response as a field scanning sensor in the terahertz range is explored.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"103 1","pages":"444-447"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76065152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has lead researchers to explore newer technologies like the CNFET(Carbon-Nanotube-Field-Effect- Transistor). Design of ternary logic circuits using CNFETs has been gaining interest recently which gives benefits for power consumption, interconnection etc when compared to binary logic. Various ternary sequential circuits have been implemented in literature. This paper proposes a new designs for sequential circuits like D-latch and D-flipflop. The proposed successor-predecessor based latch design is multiplexer based that optimises power consumption when compared to existing designs. Ternary flipflop is also designed using the proposed mux based latch design. All the proposed designs are simulated using HSPICE and a standard Stanford CNFET model. Simulation results for the proposed successor-predecessor based D-latch design and proposed D-flipflop design shows an improvement of upto 36% and 51% in power respectively, as compared to designs existing in literature.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"32 1","pages":"169-172"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86958066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The types of raw materials combined with the manufacturing processes used to produce the graphite yield the microstructural content which primarily includes graphite filler, graphitized pitch binder, and voids/defects that typically occupy approximately 20% of the volume. Among these microstructural components, porosity, microcracking (considered to be part of voids/defects) and intracrystallite nanocracking (Mrozowski cracks) heavily influence the overall properties of the material including the elastic moduli. Models describing the elastic moduli of porous, polycrystalline graphite materials have been developed to interpret experimental determinations of Young's modulus and shear modulus in oxidized graphites, and these include the effects of nano/microcracks. This work will demonstrate the role that the effects of neutron irradiation on Mrozowski cracks could have on the phenomenon of turnaround in nuclear graphites and will present directions to be pursued to account for microstructure-related effects that generally occur as a result of neutron irradiation.","PeriodicalId":6791,"journal":{"name":"2021 IEEE 21st International Conference on Nanotechnology (NANO)","volume":"417 1","pages":"289-292"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75806224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
