Electrical current and carrier density in degenerate materials with nonuniform band structure

  title={Electrical current and carrier density in degenerate materials with nonuniform band structure},
  author={A Marshak and C. M. Van Vliet},
  journal={Proceedings of the IEEE},
This paper reviews and extends the theory of electron and hole motion and density in solids with position-dependent band structure. This includes materials with graded composition, like heterojunctions, with nonuniform temperature or strain, and devices with highly doped regions, like the emitter region of modern bipolar transistors and solar cells. Size effects, such as those in short-channel MOS transistors, are not considered. Changes in the energy band edges due to spatial variations in… CONTINUE READING
