Abstract:

According to the actual growth way of graphene presence of the carbon source, four kinds of 3d grapheme-carbon nanotubes composite T structure are built, and their electron transport properties studied by combining density functional theory and the non-equilibrium green's function method. First the double probe model is built and the structure optimization is designed in ATK software, and then their transmission spectrums and electronic state density spectrum lines are analyzed. These research results can provide the reference for the 3d interconnect based on carbon nanomaterials.

Key words: graphene, carbon nanotube, 3d internation, electron transport properties
