From Anomalous to Normal: Temperature Dependence of the Band Gap in Two-Dimensional Black Phosphorus
Shenyang Huang, Fanjie Wang, Guowei Zhang +11
The temperature dependence of the band gap is crucial to a semiconductor. Bulk black phosphorus (BP) is known to exhibit an anomalous behavior. Through optical spectroscopy, here w…
Raman spectroscopy of optical phonon and incommensurate charge density wave modes in 2H-TaSe2 exfoliated flakes
Lin Cui, Qiaoling Huang, Gaomin Li +2
2H-TaSe2 is a model transition metal dichalcogenide material that develops charge density waves (CDWs).Here we present variable-temperature Raman spectroscopy study on both incomme…
Mechanisms governing phonon scattering by topological defects in graphene nanoribbons
Ziming Zhu, Xiaolong Yang, Mingyuan Huang +3
Understanding phonon scattering by topological defects in graphene is of particular interest for thermal management in graphene-based devices. We present a study that quantifies th…
Raman Spectroscopy of Graphene under Uniaxial Stress: Phonon Softening and Determination of the Crystallographic Orientation
Mingyuan Huang, Hugen Yan, Changyao Chen +3
We present a systematic study of the Raman spectra of optical phonons in graphene monolayers under tunable uniaxial tensile stress. Both the G and 2D bands exhibit significant red…
Variable Electron-Phonon Coupling in Isolated Metallic Carbon Nanotubes Observed by Raman Scattering
Yang Wu, Janina Maultzsch, Ernst Knoesel +6
We report the existence of broad and weakly asymmetric features in the high-energy (G) Raman modes of freely suspended metallic carbon nanotubes of defined chiral index. A signific…
