Intrinsic temperature (Ti) is defined as the temperature at which the intrinsic concentration ni equals the doping concentration N. Calculate the value of Ti for GaAs with doping concentration ND = 10^14 cm−3 and assuming Nc and Nv to be independent of temperature. [Given EG,GaAs = 1.43 eV, Nc=4.7 × 10^17 cm−3 and Nv=7 × 10^18 cm−3. At T=300 K kBT=0.026 eV.] Enter answer without units.
