Description
The field of nanoelectronics has experienced a significant shift with the emergence of graphene, a two-dimensional material with remarkable electronic properties. This practical demonstration will serve to present a fabrication process of a graphene-based transistor. The transistor will be prepared during the lecture in the clean room of the Laboratory of Organic Matter Physics of the University of Nova Gorica. We will delve into the fabrication techniques, with a hand-on lecture on the technique of micromechanical exfoliation, the recognition of few layer graphene by the optical microscope and fabrication of a graphene-based transistor by means of laser lithography.
