QUESTION:3 A special semiconductor material is to be "designed". The semiconductor is to be n- type and doped with 1x 10 cm donor atoms. Assume complete ionization and that Na=0. The effective density of state functions are given by Nc = Nv =1.5 x 10" cm and are independent of temperature. A particular semiconductor device fabricated with this material requires the electron concentration to be no greater than 1.01 x 10" cm at T=400K. What is the minimum value of the band gap energy?
