Abstract

Infrared radiation is by nature characterized by low photon energy and thus usually detected by semiconductor materials with small band gaps. These materials are usually produced by epitaxial growth processes. These achieve high performance but often at high cost. This motivates the development of alternative materials. Here, we aim to harness recent breakthroughs in nano-optics and in two dimensional materials to realize photodetectors that are scalable, low cost and with good performance. We report our results with materials that include PtSe₂, Cu TCNQ, bP/MoS₂, SeTe, and graphene. We furthermore report on filter array – detector array (FADA) microspectrometers.
