Abstract : Photo emission from solid to solid in MOS structures has been studied in a silicon-siliconoxide-gold structure. This study gave insight into the location of the silicon dioxide conduction band with respect to the silicon energy bands. It was also found that the number of traps is higher in p samples than in n samples. Photoemission from solids into vacuum was studied and the method of periodic Schottky deviation has been used as a tool for evaluating surface barriers of metals. By using phase matching instead of amplitude matching between the predicted curve and the experimental curve a barrier height of 7.4, 6.1 and 5.2 ev for Rhenium, Tungsten, and Molybdenum was obtained.
