Using the Energy Band Diagram shown on the right Explain the proces.pdf

  1. Using the Energy Band Diagram shown on the right: Explain the process of electron generation. Materials with large bandgap energy are called inductors OR insulators? Explain why! Consider n-type GaAs at T=300K doped to a concentration of Nd = 2 Times l016 cm-3. Assume mobility values of mu a = 6800 cm2/V-s and mu P=300 cm2/V-s. Determine the resistivity of the material (rho) Solution 1.Proceess of Electron Generation: Whne we apply the external force ,the, the electron from Valance band shift to conductance band,this shifted electron create another electron by recombination with atom and emit the electron,it will continues with near by atoms its create flow electrons 2.Materials with large bandgap energy are called Insulator.Due to large bandgap ,A large amoutn of enerygy is required to shift electrons from Valance band to conductance band
