What is Symmetric and Asymmetric Fractal Diffusion of Electron–hole Plasmas in Semiconductor Quantum Wells about?

The diffusion of photogenerated electron-hole plasmas in intrinsic InPrInGaAsrInP single quantum wells was investigated by measurements of the photoluminescence intensity profile around the illuminated area. Two kinds of w x heterostructures were investigated, one grown on InP substrate with the growth face orthogonal to the 001 direction, and the other grown on InP substrate two degrees off that orientation. The data show that the particles present a fractal diffusion described by the Levy distribution with the exponent parameter a s 1.3. In the tilted heterostructure, the diffusion is ́w asymmetric and the particles density obeys a generalized Levy distribution recently predicted by Chaves Phys. Lett. A 239 Ž . x 1998 13 .
