Silicon atoms with a concentration of 7x 1010 cm are added to gallium
arsenide GaAs at T = 400 K. Assume that the silicon atoms act as fully ionized dopant atoms and
that 15% of the concentration added replaces gallium atoms to free electrons and 85% replaces
arsenic to create holes. Use the following parameters for GaAs at T = 300 K:
