Option A: 2G Option B: … GUNN diode, PIN diode, Varactor diode, Tunnel diode, normal P-N Junction diode, Zener diode, Schottky diode, Impatt diode, Trapatt diode, baritt diode, Point Contact Diode and Hot Carrier Diode etc. TRAPATT Diode :- It is abbreviated as Trapped Plasma Avalanche Triggered Transit Device. So, GaAs are not preferred over silicon and germanium. Academia.edu is a platform for academics to share research papers. DIODE BY C.O.G. But GaAs has a major disadvantage of complex fabrication process and higher cost. Out of these materials, GaAs have highest efficiency, low noise and high operating frequencies. ABSTRACT This paper proposes an approach for obtaining a relatively simple set of equations which apply to the description of TRAPATT phenomenon and applies it to model trapped-plasma mode oscillations in a p+ n – n+ silicon diode.
