Research Abstract

A novel instrument based on an alternating current surface photovoltage (AC SPV) was successfully developed to evaluate a crystallinity of Si poly-crystal thin film nondestructively. Simultaneously, irregular AC SPV characteristics were clarified for thermally oxidized Au-, Fe-, and Cr-contaminated n-type Si single crystal surfaces, respectively. The effects of these metal impurities on thermal oxide growth of Si surfaces were also investigated.
