3-week Project:

Single crystalline graphene films can be obtained by seamless stitching on Cu(111), for this purpose, Cu(111) films on large area are usually desired. One of the methods to obtain such copper films is the contact-free annealing (CFA) method, during which copper films are not in contact with sample holders. Once the strain within the film is eliminated, grains can grow in a much faster way with the (111) facet as reported in literature. In this 3-week project, mainly a specifically designed quartz holder will be used to test whether such CFA method can be used to grow large Cu(111) grains, and the as-obtained copper films will be used for graphene growth by chemical vapor deposition (CVD) method.

 

More specifically, during the project you will

 

※   Pretreat copper foils by electropolishing to smoothen the metal surface

※   Anneal the copper foil by CFA method and the normal “contact annealing” method

※   Optimize the annealing process to obtain large copper grains

※   Grow graphene films by CVD method on copper foil

※   Graphene transfer by etching method

※   Characterize by common method, such as scanning electron microscopy (SEM), Raman and X-ray photoelectron spectroscopy (XPS).
