中文摘要	A high sensitivity photovoltaic effect has been observed in a heterojunction composed of n-type wide bandgap oxide SrTiO3-delta and p-type Si fabricated by laser molecular beam epitaxy. The responsivity of open-circuit photovoltage can reach 10(4) V/W without any amplification under zero bias for the wavelength range from visible to near infrared light in nW-mu W order. We attribute the high performance of the photovoltage responsivity to the interfacial photoelectric effects in the SrTiO3-I '/Si heterojunction. From the experimental results, some ideas can be generalized to improve photovoltaic efficiency and develop high sensitivity photodetectors with wide bandgap oxide materials and Si.
