Abstract

Low-dimensional materials such as single-wall carbon nanotubes (CNTs) and transition-metal dichalcogenides are potential materials for developing the next generation of optoelectronic devices. Understanding ultrafast dynamics in these materials is key towards this realization. Here, we study the out-of-equilibrium dynamics in electrically-biased CNTs by probing the free carriers at different time scales after photoexcitation, using terahertz emission and photocurrent measurement techniques. We then explain our results in combination with theoretical simulations using a realistic CNT band structure and taking into account all possible scattering pathways.

Filchito Renee Bagsican is a postdoctoral researcher in Okinawa Institute of Science and Technology Graduate University (OIST) in Okinawa, Japan. He earned his Ph.D. in Engineering from Osaka University in 2016. Prior to that, he obtained his Master's and Bachelor's degrees in Physics from Mindanao State University – Iligan Institute of Technology, Iligan, Philippines. He is interested in applying ultrafast techniques to study the fundamental properties of materials. His current work in OIST is in high harmonic generation to produce extreme ultraviolet radiation as a light source for time-resolved photoemission spectroscopy of low-dimensional materials.
