Exceptional and Anisotropic Transport Properties of Photocarriers in Black Phosphorus
Jiaqi He, Dawei He, Yongsheng Wang +4
We show that black phosphorus has room-temperature charge mobilities on the order of 10 cmVs, which are about one order of magnitude larger than silicon. We a…
Graphene Side Gate Engineering
Ching-Tzu Chen, Tony Low, Hsin-Ying Chiu +1
Various mesoscopic devices exploit electrostatic side gates for their operation. In this paper, we investigate how voltage-biasing of graphene side gates modulates the electrical t…
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…
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…
Thermal infrared emission reveals the Dirac point movement in biased graphene
Marcus Freitag, Hsin-Ying Chiu, Mathias Steiner +2
Graphene is a 2-dimensional material with high carrier mobility and thermal conductivity, suitable for high-speed electronics. Conduction and valence bands touch at the Dirac point…
