ABSTRACT
Electron multiplication for a series of In[sub 0.53]Ga[sub 0.47]As p-i-n diodes and hole multiplication for a n-i-p diode were measured at electric fields of 100–260 kV/cm over a temperature range of 20–300 K. The electron multiplication characteristics consistently showed positive temperature dependence at low electric fields (below ∼200 kV/cm) but exhibited negative temperature dependence at high fields. These observations explain the apparent discrepancies of the temperature dependence of the electron ionization coefficient in In[sub 0.53]Ga[sub 0.47]As in literature. In contrast, hole multiplication showed little change with temperature. © 2003 American Institute of Physics.

    A high power microwave generator based on a relativistic backward wave oscillator with a resonant reflector (BWO-RR) has been proposed in order to improve microwave conversion efficiency. In this device, the slow wave structure is separated by a modulation cavity, which significantly decreases...
