Carbon Nanotube-Based Nanophotonics
- Ultra-clean SWCNTs with enhanced emission dynamics:
- Two orders of magnitude longer spontaneous emission time (T1) compared to previously reported experiments.
- Measurement of exciton dephasing time (T2) for the first time in the time domain- 4 times longer compared to previous results.
