Tunable Bandgap in Silicene and Germanene
Zeyuan Ni,Qihang Liu,Kechao Tang,Jiaxin Zheng,Jing Zhou,Rui Qin,Zhengxiang Gao,Dapeng Yu,Jing Lu +8 more
TL;DR: Ab initio quantum transport simulation of a dual-gated silicene field effect transistor confirms that the vertical electric field opens a transport gap, and a significant switching effect by an applied gate voltage is also observed, meaning biased single-layer silicenes and germanene can work effectively at room temperature as field effect transistors.
