TL;DR: In this article, the hole effective-mass Hamiltonian for semiconductors with wurtzite structure was derived by fitting the valence-band structure near the top with that calculated by the empirical pseudopotential method.
Abstract: The hole effective-mass Hamiltonian for the semiconductors with wurtzite structure is given. The effective-mass parameters are determined by fitting the valence-band structure near the top with that calculated by the empirical pseudopotential method: The energies and corresponding wave functions are calculated with the obtained effective-mass Hamiltonian for the CdSe quantum spheres, and the energies as functions of sphere radius R are given for the zero spin-orbital coupling (SOC) and finite SOC cases. The energies do not vary as 1/R-2 as the general cases, which is caused by the crystal-field splitting energy and the linear terms in the Hamiltonian. It is found that the ground state is not the optically active S state for the R smaller than 30 Angstrom, in agreement with the experimental results and the "dark exciton'' theory.

TL;DR: In this article, the experimental thermodynamic and phase diagram data of the AlSbGaSb ternary system have been critically assessed and compared with the related experimental data.
Abstract: The experimental thermodynamic and phase diagram data of the Al-Ga-Sb ternary system have been critically assessed. With the assessed thermodynamic parameters, the pseudobinary AlSbGaSb phase diagram, the isothermal ternary sections, and the thermodynamic properties were calculated and compared with the related experimental data.

TL;DR: Using the Green function method, the authors studied the cyclotron resonance of an electron interacting with bulk longitudinal optical phonons as well as surface optical(SO) phonons in a polar crystal slab at finite temperatures.
Abstract: Using the Green function method, we have studied the cyclotron resonance of an electron interacting with bulk longitudinal optical(BO) phonons as well as surface optical(SO) phonons in a polar crystal slab at finite temperatures. It is found that the temperature dependence of magnetopolaron depends strongly on the strength of the magnetic field. The numerical results show that the cyclotron resonance mass of polaron in a slab is an increasing or decreasing function of temperature when the magnetic field is lower or higher than the resonant magnetic field region, respectively. The magnetic field and slab width dependence of cyclotron resonance mass are also studied in this paper. (C) 1999 Elsevier Science B.V. All rights reserved.
