Explain the construction and operation of Impact Ionization Avalanche TransitTime (IMPATT) diode used for microwave generation.
The Impact Ionization Avalanche Transit-Time (IMPATT) diode is a type of semiconductor device used for microwave generation. It is constructed using a three-layer structure: an n-type region, a p-type region, and an intrinsic region (also called the i-region). The i-region is typically a thin _______ _____ ____ ____ _____.
