The photoresponsive characteristics of SrTiO3-based oxide heterointerfaces at.different thicknesses and strains are investigated. In addition to the typical.persistent photoconductivity, the transient photoconductivity is observed at the.heterointerfaces below the critical thickness. More intriguingly, it shows a.transition from the transient photoconductivity to the persistent photoconductivity.for the interfaces at the critical thickness with enhancing temperatures,.which is related to the dom
