An intrinsic silicon semiconductor is uniformly

An intrinsic silicon semiconductor is uniformly

Question
A20. An intrinsic silicon semiconductor is uniformly doped with acceptors to a level of 2x1017 cm-³. At room temperature, the electron concentration in this semiconductor is found to be 5x10² cm-3. What is the intrinsic carrier concentration of this semiconductor at room temperature and describe qualitatively how would the electron concentration change if the temperature increased slightly?
