please help me to answer this question correctly. and please make sure hand writing is clear and easy to read. please help me tq Question 3 (30 marks) AIN is a direct band-gap semiconductor with a wide bandgap of 6.026eV at 300K. The empirical constants for AIN are: α= 1.799 x 10-3 eV/K and β = 1462 K. (a) The energy bandgap separates the permitted electron energy level between valance and conduction bands. G) What is the energy state at absolute 0K? (i) What is the energy state at 300K? [5 marks] [5 marks] (b) Calculate the energy bandgap of AIN at OK. [10 marks] (c) Calculate the minimum frequency and the respective wavelength required by a photon to transfer a valance electron to the conduction band at 300K in vacuum. State the electromagnetic spectrum of this photon 10 marks]
