Dynamics of Supermatrix Semiconductor Growth

Abstract

Electronic Materials Engineering and AFOSR have demonstrated a new semiconductor materials technology for electronic and optoelectronic device applications: the Supermatrix Semiconductor (SMS). SMS makes possible the 3-dimensional superlattice and a new method for engineering the properties of semiconductor materials through the synergy of 3-dimensional microstructural ordering. A CrGaAs SMS has been produced in Ingot form (2 in. long and 1 in. diameter) exhibiting a periodic rod-matrix microstructure over wafer-scale distances. Electronic, optical, and structural properties were characterized by PPL, SIMS, RBS, Auger, and x-ray diffraction and correlated to conditions of solidification. It was demonstrated that the cubic degeneracy of GaAs In the CrGaAs matrix is lifted as a result of anisotropic stress and leads to birefringence. Advances in practical processing of SMS materials, Including polishing, have also been achieved to support future device development activities. Supermatrix semiconductor.
