The general objective of the work we are developing consists of the process of fabricating devices in two-dimensional materials, including lithography, metal deposition for electrical contact patterns, morphological characterization and electrical measurements. The sample was produced using a method called Mechanical Cleaving. This method basically consists of manually separating the stacked layers of a graphite crystal repeatedly by sticking and peeling the crystal to a piece of tape. This is then attached to the silicon dioxide substrate and pressed manually so that the flakes adhere to the ...
