Orientation-dependent crossover from retro to specular Andreev reflections in semi-Dirac materials

Orientation-dependent crossover from retro to specular Andreev reflections in semi-Dirac materials

In the framework of Bogoliubov–de Gennes equation, we theoretically study the transport properties in normal-superconducting junctions based on semi-Dirac materials (SDMs). Owing to the intrinsic anisotropy of SDMs, the configuration of Andreev reflection (AR) and the differential conductance are st...
