Abstract :
The electric field and width of the avalanche region are vital while determining the performance of an IMPATT diode. In an attempt to optimize the same a new doping pattern in the form of doping steps is introduced in the avalanche zone and its effects on the terahertz characteristics of a 4H-SiC IMPATT Diode are explored. It is exciting to observe a conversion efficiency of 17.24 % from the IMPAT T diode with the proposed doping steps.
