摘要： The problem to be overcome by the present disclosure is to provide a graphite sheet with the ability to lower the contact thermal resistance at the surface of the graphite sheet. In a graphite sheet, a plurality of graphite layers are stacked one on top of another in a thickness direction. The plurality of graphite layers includes: a first graphite layer that forms an outermost layer of the graphite sheet; and a second graphite layer other than the first graphite layer. At least a part of the second graphite layer is exposed through a surface of the first graphite layer. The graphite sheet has an apparent shear strength equal to or greater than 0.1 MPa and equal to or less than 0.5 MPa as measured by SAICAS method from a depth of 0.5 m to a depth of 19 m.

摘要： The present invention is a surface-modified carbon material including chemical addends added to the surface of graphene, such that a one-dimensional periodicity corresponding to a large number of addition positions of the chemical addends can be observed in a Fourier-transformed image of a scanning probe microscopic image of the surface of graphene. The surface-modified carbon material of the present invention has a bandgap and therefore can be used as a sensor capable of electronically controlling an operation or another electronic device.
