Strain-modulated Bandgap and Piezo-resistive Effect in Black Phosphorus Field-effect Transistors
Zuocheng Zhang, Likai Li, Jason Horng +10
Energy bandgap largely determines the optical and electronic properties of a semiconductor. Variable bandgap therefore makes versatile functionality possible in a single material.…
Direct Observation of Layer-Dependent Electronic Structure in Phosphorene
Likai Li, Jonghwan Kim, Chenhao Jin +14
Phosphorene, a single atomic layer of black phosphorus, has recently emerged as a new twodimensional (2D) material that holds promise for electronic and photonic technology. Here w…
