Interfacial States and Fano–Feshbach Resonance in Graphene–Silicon Vertical Junction

Abstract

ACS Paragon Plus Environment Nano Letters 2 spectrum) and the lateral band structure of graphene (continuous energy spectrum) result in Fano-Feshbach resonance. Our results show that the conventional description of interfacial interaction in low-dimensional systems is valid only in considering the lateral band structure and its density-of-states and is incomplete for the ease of vertical transport. Our experimental observation and theoretical explanation provide more insightful understanding on various interfacial effects in low-dimensional materials, such as proximity effect, quantum tunneling, etc. More important, the Fano-Feshbach resonance may be used to realize all solid-state and scalable quantum interferometer.
