Question

Electromagnetic radiation of wavelengths ranging from 250 nm to 1100 nm fall on a
cadmium telluride (CdTe) semiconductor of bandgap energy 1.44 eV.


i. Determine the range of wavelengths (in nm) that when absorbed by the
semiconductor will produce mobile electrons to act as charge carriers.
ii. Suggest possible semiconductors that could absorb the remaining range of
wavelengths.
