In-Plane Anisotropy-Driven Directional Charge Transport in van der Waals p-n Heterojunction

Rahul Paramanik, Tanima Kundu, Soumik Das +8

Low-symmetry two-dimensional (2D) van der Waals (vdW) materials enable anisotropic charge transport, crucial for polarization-sensitive optoelectronics. In this study, a $p$-GeS/$n…
