Ishwara Bhat, in Wide Bandgap Semiconductor Power Devices, Effective mass of carries. The effective mass of electrons and holes in a band is important for the transport property and also for describing various electrical and optical properties of the material. The value of the effective mass is dependent on the local structure of the band near the band extremum and is defined by The one- or multi-band effective mass theory is used wherever this method is applicable. A summary of group theory for application in semiconductor physics is given in an Appendix. Chapter 4 deals with the statistical distribution of charge carriers over the band and localized states in thermodynamic :// Introduction The effective mass of a semiconductor is obtained by fitting the actual E-k diagram around the conduction band minimum or the valence band maximum by a parabola. While this concept is simple enough the issue turns out to be substancially more complex due to the multitude and the occasional anisotropy of the minima and ~bart/book/ 1.

At its heart are five fundamental transport phenomena: quantized conductance, tunneling transport, the Aharonov–Bohm effect, the quantum Hall effect, and the Coulomb blockade effect. The book starts out with basics of solid state and semiconductor physics, such as crystal :oso//.
