Abstract(in English) | We have grown aluminum nitride (AlN) films on 3 ?off-axis Si(110) substrates by pulsed laser deposition (PLD) and formed SiC low-temperature buffer layers on the AlN layers by ultralow pressure chemical vapor deposition using monomethylsilane (MMS; CH3SiH3) to grow SiC films on the buffer layers by PLD. We optimized the substrate temperature and MMS pressure for formation of the buffer layers to improve the crystallinity and surface roughness of the SiC films. Furthermore, graphene was formed on the SiC films on the buffer layers formed under the optimized conditions by high- temperature annealing in vacuum. X-ray photoelectron spectroscopy and Raman spectroscopy were used to evaluate the crystallinity and determine the number of layers of graphene. Annealing at 1200 ?C for 30 min resulted in the formation of 4-5 layers of graphene. It was found that employing the SiC buffer layer formed under the optimized conditions increased the growth rate of graphene, which was much higher than those of graphene on Si(110) substrates. |
