While there are many reports in literature regarding improved performance in these devices, only few reports provide detailed performance and theoretical efficiency limits in perovskite-based solar cells (PSCs). An analytical model accounting for both optical and electrical losses in a PSC has been largely unexplored. Our calculations provide a simple semi-analytical framework for the analysis of different loss mechanisms in a PSC, which enables the determination of theoretical performance and loss limits more accurately. We believe that this will aid in the design of high-performance PSCs.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"35 1 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":"75680403","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}

Modeling and Investigation of Electronic Transport Properties of Boron or Nitrogen Substitution Doped Single Layer Graphene 硼或氮取代掺杂单层石墨烯的电子输运性质建模与研究

Further, the interaction parameter paves a route to explore the vital transport properties such as scattering time $(tau)$, conductivity $(sigma)$, and mobility $(mu)$, which have been investigated for B/N substitution doped graphene in this work. The interaction parameter for undoped pristine single layer graphene is constant and independent of carrier density and depends only on the dielectric constant of the substrate material. On the other hand, the interaction parameter for B/N substitution doped graphene is extensively influenced by shifting of Dirac point, non-zero bandgap due to dopant and carrier density. From the transport properties, it has been predicted that B/N substitution doped graphene exhibits significant asymmetric electronic transport behaviour in both electrons and holes rather symmetric in pristine graphene. Consequently, substitution doping in graphene suppresses ambipolar characteristics and highly leading to enhance the ON/OFF ratio. Also, the electronic and transport properties are the essential quantities of interest while modeling the low-dimensional devices. Therefore, investigation of electronic transport properties of B/N substitution doped graphene reveals more insights in the device modeling of doped graphene in field-effect device applications.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"57 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":"84889365","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}

Here, the impact of loss on the plasmonic resonances in metal-insulator-metal slits is analyzed. The reflection of TM light in a subwavelength slit in a real metal has been calculated using mode matching theory and orthogonality principle of electric and magnetic field for a real metal exhibiting both dispersion and loss. Then the calculated reflection phase has been used to calculate plasmonic resonances. The impact of metal loss and the presented theory on plasmonic resonances is investigated. The theoretical calculations agree well with comprehensive simulations, but differ substantially from the conjugated orthogonality result, as was used in past analytical works, showing promise for simple theoretical investigation of future plasmonic MDM structures.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"134 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":"86321400","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 paper presented a miniaturized dual-mode ultrasound transducer with piezoelectric stacks and a laser ultrasound transducer.
