Abstract
In this paper, we describe the application of thin film combinatorial deposition methods to systematically control the microstructure of AlxSi(1−x) alloys through variations in composition and growth temperature. Discrete libraries of compositionally graded films have been sputter deposited onto silicon substrates to produce two structural phase regions: amorphous a-(Al-Si) and amorphous a-Si plus crystalline c-Al. The microstructure was investigated using x-ray diffraction while atomic force microscopy techniques were used to obtain surface morphology and phase distribution.
