Characterization of tunneling and free-carrier screening in coupled asymmetric GaN/AlGaN quantum discs

We present a systematic investigation of free-carrier screening in coupled asymmetric GaN quantum discs with embedded AlGaN barriers using time-integrated and time-resolved micro-photoluminescence measurements, supported by three-dimensional multi-band k.p computational modeling. Free-carrier screen...
