Abstract

Abstract : Placing 2D building blocks with lateral size differences leads to the formation of an asymmetric heterojunction, which enables evidently ionic current rectification behaviour. Abstract : Here we report on the facile formation of asymmetric heterojunctions between laterally size different 2D flakes, which leads to a prominent gradient in charge distribution at the nanocontact interface and triggers ionic diode-like transport behaviour with a rectification ratio of 110.
