The electron effective mass m_e~* can be calculated from the Kramers-Kronig transformation of electron energy loss spectra (EELS) for Ⅲ-Ⅴ semiconductor materials. The mapping capabilities of a scanning transmission electron microscope, equipped with a Gatan Enfina EELS sy...

A comparative survey of known experimental and theoretical values of heavy-hole and electron effective mass in GaAs, InAs, and A1As is presented in this work. Recommended room-temperature values of these parameters are given for the above binary solutions and for their ternary compounds. DOI: 10....
SEMICONDUCTOR PHYSICS | Outline of Basic Electronic Properties C.R. Pidgeon, in Encyclopedia of Modern Optics, 2005 Effective Mass Consider what happens to an electron when an external electric field F is applied. Suppose the electron is initially in a state k. When the field has acted on the...
Position-dependent effective masses in semiconductor theory. II A compound semiconductor possessing a slowly varying position-dependent chemical composition is considered. An effective-mass equation governing the dynamics of electron (or hole) motion using the Kohn-Luttinger representation and canoni... vo...
Small-Gap Semiconductors in Crossed Magnetic and Electric Fields It is demonstrated theoretically that in a small-gap semiconductor with large spin-orbit interaction energy a sufficiently strong transverse electric field destroys the Landau diamagnetic quantization but not the Pauli paramagnetic quant...

It is found, taking InAs/GaSb superlattice as an example, that the effective electron mass oscillates with the inverse quantizing magnetic field due to the Shubnikov-de Hass effect. The dependence of the effective mass on the magnetic quantum number in addition to Fermi energy is an intrinsic ...
By using the recently developed exact effective-mass envelope-function theory, the electronic structures of inas/gaas strained superlattices grown on gaas (100) oriented substrates are studied. the electron and hole subband structures, distribution of electrons and holes along the growth direction, optic...
The semiconductor charge carrier energy—wave vector relationship rather than that of the metal is shown to be dominant because it controls the cone of acceptance for carriers incident on the barrier from the metal side. The effective mass in the ideal Richardson constant for T-F emission is ...
