We study the physics governing nanoscale systems, in particular nanowires, nanotubes and two-dimensional materials like graphene and transition-metal dichalcogenides. Most of our nano-objects are grown in our lab, and they are then built into various kinds of devices using micro- or nano-fabrication techniques. We are particularly interested in low-dimensional physics, many-body effects, phase transitions, and electronic excitations. We work closely with the Nanoscale Optoelectronics Lab of Professor Xiaodong Xu and exploit the low-temperature expertise of Professor Oscar Vilches. We are motivated by curiosity, but we hope our work will be relevant to applications in sensing and to storage and transfer of charge, energy and information.
