Physical review B: Condensed matter and materials physics, 76(19), 0 - 0. https://doi.org/10.1103/physrevb.76.193309

We address the occurrence of conduction-band crossover in III-V self-assembled quantum dots solely due to misfit strain. Band structure analysis in terms of standard deformation-potential theory shows that Γ-X crossover can occur in the dot, while bo...

Rain rate is a physical parameter that is only defined over some spatial or spatial-temporal integration volume. The moments of rain rate fields calculated from measurements derived from integration volumes of the same shape and a range of sizes are...
