They can potentially enhance the structural efficiency of the components, which means, for a given loading condition, the section uses as little material as possible. As a matter of fact, the complete freedom in parts shape design could be exploited to increase the fatigue strength of structural components by crack arresters (CAs) design. From classical fracture mechanic theories, it is well known that when the fatigue crack meets a hole, the consequent sudden reduction of the stress concentration ahead of the crack tip promotes the arrest of the crack propagation itself. Using additive manufacturing, it is now possible to design structural components with CAs in the vicinity of crack initiation points like notches. This paper is aimed at exploring, with preliminary experiments supported by numerical analyses, this possibility. It was found that crack arresters effectively enhance the fatigue life of a notched component provided that their shape and position are designed properly.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"4 1","pages":"02SAMA02-1-02SAMA02-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86078515","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}

However, further area reduction has again driven us to technological limits. To enhance the performance of next-generation devices, Nanowire FET designs show some desirable characteristics. Furthermore, to enhance the control limitations, a slight variation of the Nanowire FET, known as the Multi-Bridge Channel FET (MBCFET) is introduced. In this research, we aim to provide an optimized design of MBCFET. Initially, an analytical study of MBCFET concerning Threshold Voltage, Subthreshold Swing (SS), and ${mathrm {I_{on}/I_{off}}}$ ratio by varying different device parameters is carried out. From the analytical study, we proposed an optimized MBCFET which exhibits superior performance compared to conventional MBCFET devices. Our optimized MBCFET fabricated with a Transition Metal Dichalcogenide (TMD): Tungsten Ditelluride (WTe2) nanosheet and Niobium pentoxide (Nb2O5) as high-k dielectric shows a Subthreshold Swing (SS) of 64. 60mV/dec and a Threshold voltage of 0. 57V at room temperature. A comparative analysis of the results shows that it provides a 2.53 times better ${mathrm {I_{on}/I_{off}}}$ ratio than the conventional devices. Finally, a comparative study of MBCFET with existing FinFET and Nanowire FET designs with nearly identical parameters is also conducted. Therefore, MBCFET’s superior performance will make it a desirable choice for Fabrication Industries to implement it in their power-efficient devices.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"63 1","pages":"01TPNS04-1-01TPNS04-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87404249","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 Formation-energy calculations suggest that the formation of the pyridine-type defects with nitrogen doping is energetically more favorable in the presence of a vacancy in comparison to its pristine counterpart. From the electronic bandstructure and density of states analysis, we have found that metallicity of the ZGNR increases with N doping, and from the transport properties analysis, it is found that monovacancy with two nitrogen-doped (Pyr-2N) results in higher current with a constant slope, defends its suitability for nanoscale interconnects.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"38 1","pages":"01TPNS03-1-01TPNS03-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89979377","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}

HighEntropy Alloys are cutting-edge technological materials containing five or more elements in relatively high concentrations (5-35 at.%) within one or several solid-state solutions. These solutions are stabilized at the nanometer scale due to the increased contribution of the mixing entropy to the Gibbs free energy, which can overcome the enthalpic contribution. Two magnetic alloys are found in FeCoNiA1xM$mathrm{n}_{mathrm{x}}$ (1.6 at.% $leq xleq$7.8 at.%) samples processed by laser metal deposition. The magnetic techniques used to screen the materials were magneto-optical imaging and magnetic force microscopy. The former allows characterizing magnetic properties within the mm-pm scale, while the latter is efficient down to the nanometer scale. Magnetic screening confirms the importance of the nanostructure in defining the alloys' magnetic properties, and the trends in the magnetic behavior as a function of the alloy composition are revealed. The experimental results suggest that it is possible to form unique alloys, which may outperform conventional magnetic materials used in various applications such as transformers, screening shields, and wind power generators.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"215 1","pages":"01NMM02-1-01NMM02-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78267200","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}
