Terahertz Physics Laboratory



Welcome to the Terahertz Physics Lab


Terahertz (THz) waves are electromagnetic waves whose frequencies lie between the microwave and infrared regions. Naturally occurring THz radiation fills up the space of everyday life providing warmth, yet this part of the electromagnetic spectrum remains the least explored region. Our research focuses on terahertz time-domain spectroscopy and ultrafast carrier dynamics in semiconductor nanostructures and carbon nanomaterials.

Quantum Dynamics of Excitions in QWs Driven by Strong THz Pulses

Terahertz Excitations of Semiconductor Microcavities

Terahertz Imaging and Spectroscopy of Graphene

Terahertz Ellipsometry of Carbon Nanotubes
