摘要：

To investigate the band structure of nonmetallic Bi2Sr2Ca1-xYxCu2Oy (x=0.4-1.0), photon-induced hopping has been employed as a new method, in which transmission spectroscopy has been carried out from 10 to 12 000 cm-1. The photon-induced-hopping conduction edge has been found at 5200 cm-1. This edge does not shift with x (x=0.4-1.0), whereas the absorption is proportional to 1-x. The charge-transfer absorption edge at 12 000 cm-1 also does not shift with x. Using this method, the bandwidth has been determined to be 5200 cm-1. Obvious midgap states have not been observed.
