Abstract: 

High-field electron dynamics in nanomaterials in the terahertz (THz) regime is an uncharted subject, yet the importance of field-control of nanostructures cannot be emphasized enough considering its potential application to high-speed electronics and quantum information processing among other areas. Our research aims to understand ultrafast charge carrier dynamics in nanomaterials such as semiconductor quantum wells, graphene, carbon nanotubes, nanoantenna-patterned vanadium dioxide and transition metal dichalcogenides driven by intense THz pulses, where the THz field is strong enough to make substantial changes in the electronic band structure of the material.
