Resistive Switching in Oxides Grown Directly on Si Wafers via Novel Electronic Mechanism

Description: Our research demonstrates Resistive Switching (RS) behavior in SrTiO3 layers grown directly on silicon substrates. This behavior is attributed to a novel physical mechanism that leverages the semiconductor band's electronic structure at the Si/SrTiO3 interface. Specifically, the conduction band offset between Si and SrTiO3 creates...
