Third harmonic generation in graphene and few-layer graphite films
Nardeep Kumar, Jatinder Kumar, Chris Gerstenkorn +4
We observe optical third harmonic generation from graphene and few-layer graphite flakes produced by exfoliation. The emission scales with the cube of the intensity of the incident…
Exciton diffusion in semiconducting single-wall carbon nanotubes studied by transient absorption microscopy
Brian A. Ruzicka, Rui Wang, Jessica Lohrman +2
Spatiotemporal dynamics of excitons in isolated semiconducting single-walled carbon nanotubes are studied using transient absorption microscopy. Differential reflection and transmi…
Ultrafast and spatially resolved studies of charge carriers in atomically-thin molybdenum disulfide
Rui Wang, Brian A. Ruzicka, Nardeep Kumar +3
Atomically-thin molybdenum disulfide is emerging as a new nanomaterial with potential applications in the fields of electronic and photonics. Charge carrier dynamics plays an essen…
Optical pump-probe studies of carrier dynamics in few-layer MoS2
Rui Wang, Brian A. Ruzicka, Nardeep Kumar +3
Femtosecond optical pump-probe technique is used to study charge carrier dynamics in few-layer MoS2 samples fabricated by mechanical exfoliation. An ultrafast pump pulse excites ca…
