▎ 摘　　要

With rapid advancement in the discovery of innovative materials, there is great opportunity for enhancing undergraduate laboratories teaching basic physics. Here, we exemplify a laboratory focused on basic concepts of semiconductors (sheet resistance, field effect, mobility) taking advantage of commercially available graphene devices, a cutting-edge material system. We present an experimental set-up and protocol that can be used to implement such a laboratory lecture. We introduce the physics concepts that will be explored and we discuss the results obtained when we carried out the described laboratory experiment.
