Germanium has a bandgap of 0.66 ev. the temperature is 25 degree celcius. (i) assuming that the material is intrinsic and that b is 2.31 e + 30 k-3cm-6, calculate the hole density. (ii) what is the dopant concentration that you would use if germanium has to have an electron concentration of 5.0e + 17 cm-3. (iii)give an example of a dopant atom that you would achieve to an electron concentration of 5.0e + 17 cm in germanium. give a clear reason for your choice considering that the material is germanium. (iv)draw the conduction band, valence band and the energy level of the dopant atom used to achieve the above electron concentration. you only need to draw the energy level of a single dopant atom. (v) what is the charge at each dopant atom location?

In a particular semiconductor, the fermi energy is located 0.4 ev above the intrinsic energy with ef – ei = 0.4 ev. assume that the silicon semiconductor is at room temperature and the intrinsic carrier concentration, ni = 1010 cm-3 . (boltzmann constant, k = 8.617 x 10-5 ev/k.) a. determine the conduction electron concentration. b. determine hole concentration. c. calculate the product of n * p. in a particular semiconductor, the fermi energy is located 0.3 ev below the intrinsic energy with ei – ef = 0.3 ev. assume that the silicon semiconductor is at room temperature and the intrinsic carrier concentration, ni = 1010 cm-3 . (boltzmann constant, k = 8.617 x 10-5 ev/k.) a. determine the conduction electron concentration. b. determine hole concentration. c. calculate the product of n * p. compare to your answer in problem 8(c). is this a coincidence? (hint: multiply the equations for n and p.)
