Abstract
Diffusion-based and ion implantation-based methods are provided for fabricating planar photodetectors. The methods may be used to fabricate planar photodetectors comprising type II superlattice absorber layers but without mesa structures. The fabricated planar photodetectors exhibit high quantum efficiencies, low dark current densities, and high specific detectivities as compared to photodetectors having mesa structures.
