然后在氧等离子体中用电子束刻蚀法去除沟道区石墨烯形成晶体管的沟道。
They then defined the transistor channel using electron-beam lithography, removing graphene outside of channel regions with an oxygen plasma.
目前为止，石墨烯带的制作都是通过自顶向下的方法，如用激光从大片石墨烯层上“剪”出带状或是“剖”开碳纳米管。
Until now, these graphene nanoribbons were made using top-down approaches, such as "cutting" the ribbons from larger graphene sheets or "unzipping" carbon nanotubes.
现在研究者正在努力优化器件结构、石墨烯性质和栅极电介质以提高晶体管性能。
The team is now busy working on improving the performance of the transistors by optimizing device structure, graphene quality and the gate dielectric.
