So, according to several papers, after graphene's production via CVD, one wets the Copper-Graphene substract with DI water. I was wondering what's the point of doing that?
Wet-transfer in graphene is a process of transferring a layer of graphene from its growth substrate to another substrate using a wet transfer method. This method involves the use of a liquid medium, such as water or a solvent, to help separate the graphene layer from its original substrate and transfer it to a new one.
Wet-transfer is necessary for graphene because it allows for the transfer of a high-quality, large area graphene layer onto a desired substrate. This is important for the fabrication of graphene-based devices, as the original substrate may not be suitable for device applications.
The main advantage of wet-transfer in graphene is that it allows for the transfer of a large area, high-quality graphene layer onto a different substrate. This method also minimizes damage to the graphene layer and allows for better control of the layer thickness.
Yes, wet-transfer can be used for other 2D materials, such as transition metal dichalcogenides (TMDs) and hexagonal boron nitride (hBN). This method is commonly used for the transfer of various 2D materials onto different substrates for device applications.
One limitation of wet-transfer in graphene is that it is a time-consuming process and requires careful handling to avoid any contamination or damage to the graphene layer. Additionally, the process may not be suitable for transferring graphene layers onto rough or non-planar substrates.
