Abstract
Synthetic layered structures, which may be semiconductor structures, are modified, both laterally and vertically, to provide novel electronic, optoelectronic, and optical properties. This is accomplished by selective intermixing of such layered structures through selective irradiation with laser beam or electron beam energy sources to effect interaction between neighboring regions, to a degree dependent on the energy density, while avoiding physical damage to the layered structures.
