Graphene stacks
WebOct 31, 2013 · The difficulty arises from the strong binding of graphene to the SiC surface. Graphene layers from multilayer graphene stacks formed on SiC could be transferred, possibly because of the weak graphene/graphene interaction (11, 12), but multilayer stacks have varying thickness, are defective, and/or are rotationally disordered (9, 10, … WebJan 21, 2024 · Like a notebook made from stacked sheets of paper, graphene stacks are thin in the vertical direction compared to their horizontal length and width. That means that the channels between the sheets are likewise oriented horizontally. That’s not ideal for filtration, because liquid has to travel a relatively long way to get from one end of a ...
