Paper Abstract

A recent report on realization/studies of Si-SiC hetero junction has given impetus to explore them for generation of rf power in double drift impact ionization avalanche transit time (IMPATT) mode. MM-wave properties of this hetero junction are compared with corresponding Si and SiC homo .junction. Interesting feature of ionization free n-SiC zone localizes the avalanche zone to less than 10% of depletion zone resulting in diode efficiency around 27% (against only 10-15% for both homo junctions Si and SiC) and three fold high rf negative resistance, which can be therefore termed as promising high rf power source.
