Room Temperature Negative Differential Resistance of CdF CdF2/CaF /CaF2 Resonant Tunneling Diode grown on Si using Nanoarea Local Epitaxy

摘要

This paper presents room temperature negative differentialrnresistance (NDR) of CdF2/CaF2 double barrier resonant tunneling diodesrn(RTDs) grown on silicon substrate using Nanoarea-Local-Epitaxy andrndemonstrates control of energy subbands in CdF2 quantum-well (QW) byrnchanging quantum-well layer thickness.
