J. Ren et al., INTEGRATED HETEROSTRUCTURE DEVICES COMPOSED OF II-VI MATERIALS WITH HG-BASED CONTACT LAYERS, Journal of crystal growth, 138(1-4), 1994, pp. 455-463
Integrated heterostructure devices (IHDs) composed of II-VI materials
in epitaxial multilayered structures for light-emitting diode and lase
r diode applications are described. These IHDs combine a light emissio
n multilayer structure with an abrupt or graded heterostructure which
includes Hg-based materials for improved ohmic contact to the upper p-
type layer of the light emitting structure.
