报告题目: Electronic Transport in Low Dimensional Systems

报告摘要: 

     In this talk, I will first introduce the quantum dots-like transport in the monolayer and bilayer graphene nanoribbons due to the presence of charged disorders. Then I will talk about the strategy for building 0-dimensional quantum dot device in a short graphene nanoribbon by spatially selective chemical doping. Next, I will present the experimental observation of helical hole spin states in Ge/Si core/shell NWs. In such a quasi-1-dimensional system, the helical state resembles re-entrant conductance features in its quantized conductance measurements. The systematic investigation will be introduced. In the end, I will show the measurements of unique chiral magneto-transport in a type-II Dirac semimetal – PtSe2. Thanks to its layered nature, the quasi-2-dimensional thin flake can be mechanically exfoliated from the bulk, in which the trivial bulk transport is significantly suppressed and the chiral magnetoresistance can be electrically tuned.
