Characterization of (111)B and (211)B CdZnTe Substrates for HgCdTe Growth
Haakenaasen, Randi; Lauten, Oda; Selvig, Espen; Kongshaug, Kjell Ove; Røer, Eivind Jülke; Hansen, Runar Wattum (2019-06-13)We have studied state-of-the-art CdZnTe (211)B and (111)B substrates and compared them to each other and to substrates from an alternative vendor. The CdZnTe surface has been characterized both as-received and after growth ... -
Effect of the Series Resistance on the Current Response of a HgCdTe Avalanche Photodiode Under High-intensity Nanosecond Irradiation
Storebø, Asta Katrine; Brudevoll, Trond; Selvig, Espen; Hansen, Runar Wattum; Lorentzen, Torgeir; Haakenaasen, Randi (2022-05-10)We investigate the nonlinear signal current response of a Hg0.72Cd0.28Te avalanche photodiode (APD) irradiated by high-intensity, finite-duration laser pulses. At high irradiation levels and/or high gains, carrier-induced ...
