A heterojunction is formed between two different materials: semiconductor A and semiconductor B, where B has a larger band gap than A. A is p-doped to 10^17 cm-3 and B is n-doped to 10^15 cm-3. Assume all dopants are ionized, and the doping concentrations are >> ni for A and B. How will the widths of the depletion regions in A and B compare to each other, and why?

A solar cell is built from a semiconductor material, such as Si, in contact with a metal. As we will see later, when the semiconductor is doped, an internal voltage is created within the semiconductor. When photoelectrons are produced via the photoelectric effect, these freed electrons move due to this internal voltage, creating electric current. (a) If silicon’s work function (i.e. the energy to free an electron from an atom) is 1.2 eV, what is the maximum photon wavelength that...

GaAs is a compound semiconductor with the diamond-cubic crystal structure. The crystal structure can also be thought of as FCC with a two-atom basis, where Ga is at (0,0,0) and As is at (1/4, 1/4, 1/4). When Si is doped into GaAs, it can either substitute for Ga or for As and whether Si acts as a p-type or n-type dopant depends on which site the Si occupies. Briefly explain why Si is an n-type dopant when it substitutes for...
