Question: Assume that an unknown semiconductor has Eg=1.1eV and Nc=Nv. It is uniformly doped with 1015 cm−3 donors, where the donor level is 45meV below the conduction band edge Ec. Given that Fermi level EF is 0.25eV below Ec at 300 K, should you use the Boltzmann distribution or the Fermi-Dirac distribution for calculating the electron and ...

The energy gaps between the valence and conduction bands are called band gaps. For silicon, the band gap is 1.1eV; for fused silica glass, it is 9.3eV. Part A. What is the wavelength λ of a photon that has energy 1.1eV? Express your answer in nanometers to two significant figures.

Question: A semiconductor has a bandgap of 1eV, and effective density-of-states, Nc=1019 cm−3, Nv=4×1019 cm−3, electron and hole mobilities of =4000 and 2500 cm2/V s, respectively. It is subjected to the following potentials at the various locations as follows (assume linear variation of potentials between locations): Point A at x=0 ...

Correct option is B. $$1.6\times 10^{-19}J$$ $$1\ eV$$ is the unit of energy which is used to denote the small amount of energy at electronic level.
