Abstract: B32.00005 : 2-D Materials Modelling: from Transistors to Majorana Fermions*
1:54 PM–2:30 PM
(Ecole Polytechnique Federale de Lausanne)
Through density functional theory (DFT), the existence of more than 1,800 2-D materials was recently predicted. Among them there might be components with better transport properties than TMDs. We therefore selected 100 monolayers out of this database of 2-D materials, combined DFT and quantum transport to simulate their “current vs. voltage” characteristics, and identified 13 candidates with both n- and p-type ON-state currents larger than what Si FinFETs are expected to deliver in the future. The results of these theoretical investigations will be presented in this talk, together with the possible application of conventional and exotic 2-D materials as hosts for Majorana Fermions.
