Semimetal Contacts to Monolayer Semiconductor: Weak Metalization as an Effective Mechanism to Schottky Barrier Lowering

Tong Su, Yueyan Li, Qianqian Wang +3

Recent experiment has uncovered semimetal bismuth (Bi) as an excellent electrical contact to monolayer MoS${}_2$ with ultralow contact resistance. The contact physics of the broader…
