โœฆ Synopsis

The nature and origin of the Fermi-liquid states in high-Tc superconductor have been studied by angle-resolved photoemission and inverse photoemission spectroscopies on Bi2Sr2Ca1_xYxCu20a (x=O.O to 0.5). The result shows that impurity-like states or mid-gap states are created in the charge-transfer gap by hole-doping.

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
