A modified core-to-valence band maximum approach is applied to calculate band offsets of strained III/V semiconductor hetero junctions. The method is used for the analysis of (In,Ga)As/GaAs/Ga(As,Sb) multi-quantum well structures. The obtained offsets and the resulting bandstructure are used as input for the microscopic calculation of photoluminescence spectra yielding very good agreement with recent experimental results.

Half-occupation approach for the ab initio calculation of strained Ga(AsSb)/GaAs valence band offsets
An ab initio based scheme for the determination of the valence band offset between different III–V semiconductor systems is presented on the example of GaAs and Ga(AsSb) pseudomorphically strained to


A method for determining band offsets in semiconductor superlattices and interfaces
The long-standing problem of determining band offsets at semiconductor interfaces is readdressed and a new method for obtaining these values is proposed. Ab initio self-consistent pseudopotential
Revised ab initio natural band offsets of all group IV, II-VI, and III-V semiconductors
Using an all-electron band structure approach, we have systematically calculated the natural band offsets between all group IV, III-V, and II-VI semiconductor compounds, taking into account the
Valence band offset in AlAs/GaAs heterojunctions and the empirical relation for band alignment
The valence band offset in AlAs/GaAs heterojunctions is found to be 0.45±0.05 eV from analysis of charge transfer versus undoped spacer layer thickness. This result and several recent experiments on

A series of (Ga, In)As/GaAs/Ga(As, Sb) multi-quantum well heterostructures is analyzed using temperature- and power-dependent photoluminescence (PL) spectroscopy. Pronounced PL variations with sample
Calculated natural band offsets of all II–VI and III–V semiconductors: Chemical trends and the role of cation d orbitals
Using first-principles all-electron band structure method, we have systematically calculated the natural band offsets ΔEv between all II–VI and separately between III–V semiconductor compounds.
Band offset determination of the GaAs/GaAsN interface using the density functional theory method
The GaAs/GaAsN interface band offset is calculated from first principles. The electrostatic potential at the core regions of the atoms is used to estimate the interface potential and align the band
Theory of semiconductor heterojunctions: The role of quantum dipoles
At any semiconductor heterojunction there is an interface dipole associated with quantum-mechanical tunneling, which depends on the band “lineup” between the two semiconductors. When the interface
Band parameters for III–V compound semiconductors and their alloys
We present a comprehensive, up-to-date compilation of band parameters for the technologically important III–V zinc blende and wurtzite compound semiconductors: GaAs, GaSb, GaP, GaN, AlAs, AlSb, AlP,
Universal alignment of hydrogen levels in semiconductors and insulators
Hydrogen strongly affects the properties of electronic materials. It is always electrically active, and usually counteracts the prevailing conductivity of the semiconductor. In some materials,
