Description
Silicon photomultipliers (SiPMs) had a transformational impact on experiments in high-energy and astrophysics. However, the SiPM is intrinsically limited in its response below 300 nm, a critical wavelength range for liquid noble scintillation detectors. We investigate AlGaN and GaN semiconductors, which have a tunable band gap and better sensitivity in the UV. With the availability of clean enough substrates, we successfully fabricated single GaN photodiodes and demonstrated UV sensitivity and Geiger-mode operation. I will give a status update and present results from our latest devices fabricated this year.
