摘要:

当在SiC(0001)上形成外延石墨烯层时,第一碳层(称为“缓冲层”)虽然相对容易合成,但不具有石墨烯的期望的电性质。导电性差是由于通过共价键合到SiC衬底的石墨烯π带的破坏。在这里,我们表明,它是可能的恢复石墨烯π带通过使用低温,CMOS兼容的过程中,不损坏石墨烯层的缓冲层和SiC衬底之间插入一个薄的氧化物层。

英文摘要:

When epitaxial graphene layers are formed on SiC(0001), the first carbon layer (known as the "buffer layer"), while relatively easy to synthesize, does not have the desirable electrical properties of graphene. The conductivity is poor due to a disruption of the graphene pi-bands by covalent bonding to the SiC substrate. Here we show that it is possible to restore the graphene pi-bands by inserting a thin oxide layer between the buffer layer and SiC substrate using a low temperature, CMOS-compatible process that does not damage the graphene layer.
