Homogeneous (np) and Heterogeneous (Np) Semiconductor Junction Fundamentals

This chapter examines in detail the structure, underlying physics and operation of the two fundamental building blocks of all semiconductor devices—the homogeneous and heterogeneous semiconductor junction. This chapter builds on the Fermi energy|level concept and introduces the energy band diagram for a given semiconductor junction. The energy band diagram embodies every detail of how a semiconductor device works. This chapter explains a step-by-step method for constructing the energy band diagram of a semiconductor device.
