Imaging Carrier Inhomogeneities in Ambipolar Tellurene Field Effect Transistors
Samuel Berweger, Gang Qiu, Yixiu Wang +7
Developing van der Waals (vdW) homojunction devices requires materials with narrow bandgaps and simultaneously high hole and electron mobilities for bipolar transport, as well as m…
