Diamond is a wide-band-gap material with large donor and acceptor ionization energies. In principle, at room temperature and below, the Fermi energy is pinned close to the donor or acceptor level, depending on which is present in the higher concentration.

Optical transition to the Fermi level in NaxWO3
Physics Letters A, 1972Abstract Evidence is given of an optical transition to the Fermi level in metallic Na x WO 3 . The transition energy depends on the stoichiometric index x . The data allow to evaluate an average m ∗ .

A simple apparatus demonstrates the dependence of Fermi level upon the temperature and impurity content of a semiconductor. Electrons are represented by ball bearings and states are represented by holes in a plastic sheet. A Fermi probability function template is positioned in energy to accommodate precisely the number of “electrons” originally put ...

A Fermi‐Level‐Pinning‐Free 1D Electrical Contact at the Intrinsic 2D MoS2–Metal Junction
Advances in Materials, 2019Currently 2D crystals are being studied intensively for use in future nanoelectronics, as conventional semiconductor devices face challenges in high power consumption and short channel effects when scaled to the quantum limit.

Fermi level and current transport of Bi12GeO2
Journal of Applied Physics, 1987A photoelectrochemical resistor was constructed using a bismuth germanium oxide electrode and a liquid junction. Current transport consists of the oxidation and reduction of water by holes and electrons, and the device exhibits ideal current voltage characteristics with a ratio of light to dark current greater than 104.

Quantum oscillations of the fermi level in metals
Physics Letters A, 1970Abstract It is shown that an effect reported by Caplin and Shoenberg and ascribed to oscillations of the Fermi level in lead, probably had its origin in oscillations of the Hall potential associated with eddy currents induced by the time varying magnetic field.

Level density of degenerate Fermi systems
Nuclear Physics, 1958Abstract Model independent expressions for the level density of systems of non-interacting Fermions are given in a form that is suitable for treating degenerate systems. No formal distinction is made between discrete and continuous distribution of the single Fermion states.

Theory of the Fermi-level energy in semiconductor superlattices
Physical Review B, 1991A theoretical study of the properties of the Fermi level in semiconductor superlattices (SL's) is made which is based upon the carrier occupation of the minibands in thermal equilibrium. We find, for a fixed carrier density and temperature, that the SL Fermi level can differ significantly from that obtained using commonly employed three-dimensional ...

The Fermi level is the maximum energy of the electrons in a material. Effectively there is a Fermi equation: EF = E max. This chapter examines the discrete electron energy levels in individual atoms as a consequence of the Pauli exclusion principle, the
