Progress on nbn infrared detectors

WebJan 5, 2014 · There has been significant progress on development of MCT on silicon substrates, but good performance has been limited to the MWIR band only. Moreover, MCT is characterized by low electron effective mass resulting in excessive leakage current [ 7 ]. The InSb detectors do not cover the LWIR spectral range.
