| Outline of Final Research Achievements |
We achieved the following milestones over the course of our project: (1) successful integration of carbon nanotubes (CNTs) in photoconductive antenna devices, (2) demonstrated their promising efficiencies as terahertz (THz) emitters, and (3) showed that THz emission spectroscopy is a powerful tool in unraveling quasiparticle dynamics in low dimensional materials.

| Academic Significance and Societal Importance of the Research Achievements |
We were able to get a clearer understanding of dynamics of free carriers and excitons in carbon nanotubes. From a scientific standpoint, this demonstrates the drastically different behavior of low-dimensional materials. It also brings us closer to their application in future optoelectronic devices.
