GaAs, AlAs, and AlxGa1−xAs: Material parameters for use in research and device applications
TL;DR: In this article, a review of the properties of the Al x Ga1−x As/GaAs heterostructure system is presented, which can be classified into sixteen groups: (1) lattice constant and crystal density, (2) melting point, (3) thermal expansion coefficient, (4), lattice dynamic properties, (5) lattices thermal properties,(6) electronic-band structure, (7) external perturbation effects on the bandgap energy, (8) effective mass, (9) deformation potential, (10) static and

Near‐band‐gap photoluminescence from pseudomorphic Si1−xGex single layers on silicon
TL;DR: In this article, an analytical expression for the exciton energy gap at 4.2 K valid for x < 0.24 was derived from the no-phonon line energies: ESX(x) = 1.155−0.874x+0.376x2 eV.

Photoluminescence investigation of InGaAs‐InP quantum wells
TL;DR: In this article, the photoluminescence of nominally undoped quantum wells is studied as a function of temperature and excitation power, and the role of an excitonic process in 4K radiative recombinations is pointed out.
