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.

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 ...

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.

Fermi Level in Amorphous Antimony Films
Physical Review, 1954Films of antimony were deposited by evaporation on interchangeable emitters in concentric-sphere, retarding-potential phototubes. Below thicknesses of about 300 A, they behaved as semiconductors. The Fermi level lay about 0.1 ev above the occupied band.

Fermi-Level Pinning in Nanocrystal Memories
IEEE Electron Device Letters, 2007The nanocrystal (NC) work-function engineering, which plays an important role on the NC memory characteristics such as memory window and retention time, were long regarded as a matter of choice on NC materials. In this letter, we report opposite polarities of charge storage in Au NC memories with different control oxides. The effective NC work function

Fermi level, work function and vacuum level
Materials Horizons, 2016Electronic levels and energies of a solid, such as Fermi level, vacuum level, work function, ionization energy or electron affinity, are of paramount importance for the control of device behavior, charge carrier injection and transport.

Stabilization of the Fermi level in photochromic glasses
Philosophical Magazine B, 1984Abstract Photochromic glasses doped with thallium, iodide and cadmium have been found not to show the superlinear relationship between equilibrium darkening and excitation intensity which was reported previously for undoped photochromic glasses.

Unpinning of the Fermi Level on GaAs by Flowing Water.
Applied Physics Letters, 1987Unpinning of the Fermi level on GaAs (100) surfaces by photochemical reactions resulting from simultaneous exposure of specimens to flowing water and light was recently reported. We discuss here a series of experiments carried out to provide further information on the changes in surface electronic structure responsible for unpinning of the Fermi level ...

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 corresponding energy bands in a material composed of many atoms or molecules, and ...

Adsorption-induced Fermi level pinning
Physics of the Solid State, 2008The adsorption-induced Fermi level pinning is shown to occur at the coverages Θ* corresponding to a shallow extremum or saturation of the work function of the system. Equations for Θ* are derived within a modified Anderson-Newns adsorption model. Experimental data on the adsorption of atoms of alkali, alkaline-earth (Ba), and rare-earth metals and ...
