(a) (b) (c) Draw the face-centered cubic cell and determine its packing fraction. State and explain the assumptions you have made. An electron is subjected to a potential difference of 10 kV in vacuum. (i) Find the velocity and wavelength of the electron. (ii) If a photon has the wavelength of the electron in Q1(b)(i), calculate the energy of the photon in unit of eV. Apply the energy band diagram to explain why an intrinsic semiconductor is conductive and that its conductivity increases with temperature.
