Research Interests

Jairo Velasco Jr.’s research focuses on discovering, understanding and exploiting novel physical phenomena that emerge in layered 2D materials. In particular, he is interested in probing the electronic structure of nanoscale devices based on these new and exciting materials. To perform these studies his lab employs several techniques such as low temperature transport, scanning tunneling microscopy (STM), and advanced nanofabrication.
