CHAPTER 4:apply these concepts specifically to asemiconductor material. CHAPTER 4:use thedensity of quantum statesin theconduction bandand thedensity of quantum statesin thevalence bandalong with theFer mi-Diracprobability functionto determine theconcentrationof electrons and holesin the conduction andvalence bandsFriday, September 20, 2013 Tennessee Technological University2 EQUILIBRIUM , or thermal EQUILIBRIUM , implies thatno externalforcessuch as voltages, electric fields, magnetic fields, ortemperature gradients are acting on the SEMICONDUCTOR .
Chapter 4: use the density of quantum states in the conduction band and the density of quantum states in the valence band along with the Fermi-Dirac probability function to determine the concentration of electrons and holes in the conduction and valence bands ... atoms or defects.
