Abstract For randomly nucleated SiGe/Si(001) islands. a significantly stronger blue-shift of the PL spectra as a function of the excitation intensity is observed when compared to islands grown on patterned substrates side by side within the same run in a solid source molecular beam epitaxy chamber. We ascribe this different PL behavior to the much larger inhomogeneity of the Ge distri... https://lecoureures.shop/product-category/course-a-pied-accessoires-hydratation-bouteille/
