Graphene based switch

ORAL

Abstract

We investigate both suspended and non-suspended SiO2 substrate-supported graphene based switch devices, which can be switched ``OFF'' by applying pulses of 8V and ``ON'' by pulses of 4V. In addition to the I-V characteristics, we also investigate the statistical behavior of the switching rate and ON state conductance. Conductance switching is observed in suspended as well as non-suspended devices. Our experimental results suggest that the observed conductance switching in SiO2-supported devices results from a combination of the switching behavior of the underlying SiO2 substrate as well as the switching behavior of the graphene break junction alone.
