Abstract
A graphene sheet and a method of manufacturing the graphene sheet are provided. The method includes: growing a graphene sheet on a graphene growth support by applying carbon sources and heat to the graphene growth support, the graphene growth support including a carbonization catalyst; and forming at least one ripple on the graphene sheet by cooling at least one of the graphene growth support and the graphene sheet, wherein the graphene growth support and the graphene sheet have different thermal expansion coefficients.
