   Abstract:
   In this paper, it is demonstrated that RHEED data obtained during the formation of the interfaces in AlGaSb-InAs HEMT devices can be used to model device important epitaxial layer electrical performance parameters. RHEED intensity oscillations of the specular spot are analyzed using principle component analysis (PCA) and modeled using error backpropagation (BP) neural networks
