Dynamics of intrinsic and nitrogen-induced exciton emission in indirect-gap Ga 1 − x Al x As
TL;DR: In this paper, the decay rate depends strongly on excitation intensity and on temperature (for 2lTl30$ K) while the position and width remain unchanged. But the authors show that in the low-temperature, low-excitation limit, the nonexponential decay, and its dependence on $x, can be quantitatively explained in terms of emission from a small number of localized indirect excitons scattered by alloy fluctuations.

Structural Phase Transitions in PrAlO 3
Journal ArticleDOI
Microscopic order parameters in PrAl O 3
TL;DR: In this paper, a spin Hamiltonian whose largest term is an almost axial second-rank tensor has been studied in the temperature range 4.2 to 295 K, where the symmetry is almost exactly tetragonal.
