Quantized Conductance through Surface States in High Quality Three-Dimensional Dirac Semimetal Cd${}_3$As${}_2$ Nanowire/Nanoribbon p-n Junctions

Sungjin An, Zhuo Bin Siu, Vardan Kaladzhyan +8

We report the observation of quantized conductance in high-mobility three-dimensional Dirac semimetal Cd${}_3$As${}_2$ nanowire and nanoribbon p-n junctions. By employing suspended dev…
