Abstract: Heterojunctions of monolayer graphene and silicon, which form shallow junctions with enhanced photoresponse, have emerged as an attractive candidate for highly sensitive weak-light ...

Abstract: The near-field-focused (NFF) beam design is a nonlinear 3D problem, which is significantly different with the far-field case. In this paper, a method of 3D beamforming, i.e., 3D polarization ...
