Electron Velocity Enhancement in Polarization-doped AlGaN

Electron Velocity Enhancement in Polarization-doped AlGaN

Three-dimensional electron gas/slabs (3DEG/S) can be obtained using the technique of polarization bulk doping in graded AlGaN semiconductor layer on GaN. Transport characteristics of the graded AlGaN are investigated experimentally through nanosecond-pulsed measurements. The measured current-voltage...
