Investigation of quantum transport of MoS2 nanoribbons via maximally locolized wannier functions MLWF Fatemeh Tabatabaei fs tabatabaei@ph iut ac ir November 13 2017 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran University Code IUT 77142 Degree M Sc Language Farsi supervisor Dr I Abdolhosseini Sarsari abdolhosseini@cc iut ac ir Abstract In recent decades one dimensional 1D nanostructures have been extensively investigated because of their interesting properties and their mesoscopic physics Among them carbon nanostructures are the best studied in both theoretical and experimental elds On the other hand carbon based nanostructures are not suitable for all applications because of their small bandgap Fortunately a good alternative to carbon based systems is a class of inorganic layered materials which exhibit di erent properties and also could be synthesized in the form of nanotubes and nanoribbons These systems could open the spectrum of applications of one dimensional systems Molybdenum disul de MoS2 is layered transition metal di calcogonide TMDC semiconductor that has attracted considerable interest because of its properties The extended bloch functions are used frequently for description of crystal elec tronic behavior in reciprocal space But this extended representation isn t ap propriate for calculation of properties that relatated to electron behavior in real space such as electronic transport that we want to investigate A good approach for description electronic behavior in real space is use set of localized function such as maximally localized wannier functions MLWFs that obtain from ab ini tio calculation and we use that in this work In this work First we studied about MoS2 s properties and then the Marzari and Vanderbilt algorithm for nding the maximally localized wannier functions and the Green s function approach for obtain quantum transport of one dimensional sysytem is introduced At the end We investigated e ect of width and strain on quantum transport for MoS2 armchair nanoribbons Keywords T M DC M oS2 wannier f unstion quantum transport one dimensional local orbital
