Nanowire based Avalanche Photodiodes for extended shortwave infrared detection

This PhD project focuses on the fabrication of nanowire-based avalanche photodetectors for extended short-wave infrared (e-SWIR) detection, targeting wavelengths between 1.7 µm and 2.5 µm. To achieve tunable detection in this range, InAs1–xPx/InP nanowire heterostructures may be employed. The fabrication process involves advanced semiconductor techniques, including MOCVD growth, sputtering, and lithography. This project will be carried out in collaboration with KTH Royal Institute, and a company IR Nova ( a leading Swedish-based company in production of infrared cameras)
