Silicon (Si) is doped with boron (B) (an acceptor) at a concentration of 1015 cm-3 . (a) How could you calculate the chemical potential? Explain briefly. (b) What are the minority and majority carriers in this doped Si? (c) Sketch the concentration of holes as a function of temperature. (d) How could you calculate the conductivity as a function of temperature? Make a sketch of the conductivity vs. T. (e) Sketch the energy band diagram in detail for this system and mark all parameters in this diagram. Additional info: m* e / me =0.60 and m* h / me =0.28 and Eg = 1.1 eV.
