关于石墨烯的机械剥离方法
|
||
|
我在看文献的时候发现有一段描述实验方法的看不懂，麻烦哪位朋友用通俗的话给小弟讲一下，谢谢，下面是原文： To extract such 2D crystallites, we used a simple but effective procedure. A fresh surface of a layered crystal was rubbed against another surface (virtually any solid surface is suitable), which left a variety of f lakes attached to it (the rubbing process can be described as similar to ‘‘drawing by chalk on a blackboard’’). Unexpectedly, among the resulting f lakes we always found single layers. Their preliminary identification amid thicker f lakes and other residue was done in an optical micro- scope. |
