โฆ Synopsis
Angle-resolved inverse photoemission spectroscopy was performed on a Bi2Sr,CaCu20s single crystal to study the electronic structure in the vicinity of the Fermi level. Inverse photoemission intensity shows two maxima at about 0.2 TX and 0.6FX from the F point along the TX direction, suggesting that there are two bands crossing the Fermi level. The present experimental result was compared with angle-resolved photoemission results and band structure calculations.

A comparative angle-resolved photoemission measurement has been performed on nonsuperconductive BiZSrZCa0.4Y0.6CuZ08 and superconductive Bi2Sr2CaCu20s to study the nature and origin of the electronic states near the Fermi level. It was found that hole-doping does not cause a rigid shift of the densi
