In general, the hydrogenated-(C-H) nano-diamond Metal Oxide Semiconductor Field Effect Transistor (MOSFET) depicts the normally-on status (depletion mode). In this paper, we investigate the interface charge effect on C-H diamond to confirm the normally-on operation, then show the characterization of surface charge effect on device operations, including normally-off with a controlled gate voltage and the nature charge of the power device. To study the corresponding effects, we simulate the two-dimensional (2D) C-H nano-diamond MOSFET under several surface charge models. These negatively charged sites or acceptors are scattering centers for carrier (holes) transport near the C-H surface. When FET operation can be realized without negatively charged sites, channel mobility is not limited by these sites and is enhanced by a factor of 3–4. The results confirm that the two-dimensional hole gas (2DHG) close to the surface indicates a p-type channel due to the dipole effect between hydrogenated diamond and the negative charge of Al2O3. The normally-off operation is achieved to realize a safety point for the power device. The evaluation results also show that the threshold voltage shifts to a negative value in a positive charge model, given that in principle, this state is not feasible without an oxidation layer or doping.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"16 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73089569","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}

Because of their extremely high quantum efficiency, light-emitting diodes (LEDs) and lasers are becoming important applications of perovskites. Among them, several low-dimensional perovskites or related materials have attracted more attention due to either controversial luminescence mechanism or peculiar edge emission. In this talk, I will first discuss these controversies and challenges to resolve them, I will then introduce our recently developed techniques to resolve the controversies and identify the origin of luminescent centers. Specifically, same-spot photoluminescence (PL) -Raman/IR is firstly used as an effective strategy to correlate PL to the structure in a direct one-to-one relationship, pressure-dependent PL-Raman is then developed as a dynamic probe to excludes point defects as a possible mechanism.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"41 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86274391","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}

While previously shown for microfluidics, OSTE+ has not yet been embedded with functional (e.g., magnetic) particles. We demonstrate that a magnetic OSTE+ using a matrix polymer of OSTEMER 324 Flex embedded with 25% by weight rare earth ((Nd0.7 Ce0.3)10.5Fe83.9B5.6) magnetic powder remains flexible after photopatterning, can be permanently magnetized, and retains a permanent magnetic field for at least 15 months. We develop a fabrication flow for this new material, as well as determine its ultraviolet (UV) curing times. Further development of magnetic OSTE+ could advance the integration of flexible M-CP microactuators into mass-manufacture, as OSTE+ integrates well with diverse substrates and can be tailored to have different ranges of Young's modulus, allowing for flexible actuators to be built into an otherwise rigid device.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"78 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83940580","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 CSRRs incorporated inside the patch (A1) give a major contribution to the performance of the antenna. The simulation results show an improvement of the reflection coefficient $vertmathrm{S}_{11}vert$ from −20 dB to −38 dB for A2, and of the directivity from 4.68 dBi to 5.68 dBi when considering A1. The paper also proposes the fabrication of a metasurface-based patch antenna loaded with a carbon nanotube (CNT) thin layer for detection of deoxyribonucleic acid (DNA). The measured results demonstrate a frequency shift of about 69 MHz and a phase shift of about 28° for Al loaded with both CNTs and DNA in comparison with the same antenna loaded just with CNTs. In the case of A2, the frequency shift and the phase shift of the antenna loaded with CNTs and DNA become equal to 704 MHz and 121°, respectively.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"58 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86903075","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}
