Wetting layer and size effects on the nonlinear optical properties of semi oblate and prolate Si0.7Ge0.3/Si quantum dots

Autor: Vinod Prasad, Francis Dujardin, M. Farkous, Varsha, David Laroze, El Mustapha Feddi, M. Kria, L.M. Pérez

Publikováno v: Current Applied Physics. 25:1-11

Semi oblate and semi prolate are among the most probable self-organized nanostructures shapes. The optoelectronic properties of such nanostructures are not just manipulated with the height and lateral size but also with the wetting layer element. The
