石墨烯中室温可逆逻辑门的增强结构

Enhanced architectures for room-temperature reversible logic gates in graphene

Daniela Dragoman, Mircea Dragoman

摘要:

我们表明,可逆的两个和三个输入的逻辑门,其中我们提到的通用Toffoli门,可以实现与三个倾斜的门控电极图案上的单层石墨烯片。这些低耗散栅极是基于石墨烯中弹道载流子的独特性质,其在传输中诱导带隙的出现以获得适当的势垒。本文提出的增强型结构的可逆逻辑门实现提供了显着的设计简化相比,基于场效应晶体管电路和潜在的高频操作的标准方法。

英文摘要:

We show that reversible two- and three-input logic gates, among which we mention the universal Toffoli gate, can be implemented with three tilted gating electrodes patterned on a monolayer graphene flake. These low-dissipation gates are based on the unique properties of ballistic charge carriers in graphene, which induce the appearance of bandgaps in transmission for properly potential barriers. The enhanced architectures for reversible logic gate implementations proposed in this paper offer a remarkable design simplification in comparison to standard approaches based on field-effect transistor circuits and a potential high-frequency operation.
