Abstract

Hole doping in the YBa₂Cu₃O_7-X in an oxide heterostructure was analyzed. The current-voltage and photovoltaic properties of YBa₂Cu₃O_7-X were also observed under ultraviolet light irradiation at room temperature. The maximum surface hole carrier density injected was found to be 3.5*10¹³ cm^-2 at L=44 mW/cm². The results show that the photocarrier injection technique could be used in transition metal oxides to control the hole carrier density.
