Abstract

Models of the densities of states of amorphous graphene and graphene-like binary compounds are proposed. The models are used for estimations of the quantum capacitance of these structures. It is shown that amorphization reduces the quantum capacitance. The same effect takes place if graphene or a graphene-like compound interacts with a metal substrate. At the same time, in the case of a semiconductor (insulator) substrate, the quantum capacitance increases.

非晶和外延石墨烯样化合物的量子电容的模型估计

摘要

提出了无定形石墨烯和类石墨烯二元化合物的状态密度模型。该模型用于估计这些结构的量子电容。结果表明，非晶化降低了量子电容。如果石墨烯或类石墨烯化合物与金属基材相互作用，则会产生相同的效果。同时，在半导体（绝缘体）衬底的情况下，量子电容增加。
