摘要:
There is provided a fabrication method for an AA stacked graphene-diamond hybrid material by converting, through a high temperature treatment on diamond, a diamond surface into graphene. According to the present invention, if various types of diamond are maintained at a certain temperature having a stable graphene phase (approximately greater than 1200° C.) in a hydrogen gas atmosphere, two diamond {111} lattice planes are converted into one graphene plate (2:1 conversion), whereby the diamond surface is converted into graphene in a certain thickness, thus to fabricate the AA stacked graphene-diamond hybrid material.

摘要:
Disclosed is a method for fabricating graphene ribbons, comprising: preparing a graphitic material comprising stacked graphene helices; and cutting the graphitic material in a short form by applying energy to the graphitic material; and simultaneously or afterward, decomposing the graphitic material into short graphene ribbons. This method provides a mass production route to graphene ribbons.
