Abstract

Official abstract text for this publication.

A graphene device may include a channel layer including graphene, a first electrode and second electrode on a first region and second region of the channel layer, respectively, and a capping layer covering the channel layer and the first and second electrodes. A region of the channel layer between the first and second electrodes is exposed by an opening in the capping layer. A gate insulating layer may be on the capping layer to cover the region of the channel layer, and a gate may be on the gate insulating layer.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a graphene device, the method comprising: forming at least one stacked structure on a first substrate, the at least one stacked structure including a sacrificial layer, a catalyst layer, and a graphene layer sequentially stacked thereon; adhering a second substrate onto the at least one stacked structure; and separating the first substrate by etching the sacrificial layer; wherein the etching comprises one of dry etching and w…
