摘要：
Visible electroluminescence has been achieved from a device based on the SrTiO3/p(+)-Si heterostructure, in which the SrTiO3 film is deposited by a sol gel process on silicon substrate. When applied with sufficient forward bias with the positive voltage connecting to the p(+)-Si, broad visible emissions peaking at similar to 550 nm occur. The self-trapped excitons relevant to oxygen vacancies in SrTiO3 are proposed to be responsible for the visible emissions from the SrTiO3/p(+)-Si heterostructured device.
