Giant Hall photoconductivity in narrow-gapped Dirac materials
Justin C. W. Song, Mikhail A. Kats
Carrier dynamics acquire a new character in the presence of Bloch-band Berry curvature, which naturally arises in gapped Dirac materials (GDMs). Here we argue that photoresponse in…
Phonon transport in a one-dimensional harmonic chain with long-range interaction and mass disorder
Hangbo Zhou, Gang Zhang, Jian-Sheng Wang +1
Atomic mass and interatomic interaction are the two key quantities that significantly affect the heat conduction carried by phonons. Here, we study the effects of long-range (LR) i…
Large Electronic Anisotropy and Enhanced Chemical Activity of Highly Rippled Phosphorene
Andrey A. Kistanov, Yongqing Cai, Kun Zhou +2
We investigate the electronic structure and chemical activity of rippled phosphorene induced by large compressive strains via first-principles calculation. It is found that phospho…
The Role of H2O and O2 Molecules and Phosphorus Vacancies in the Structure Instability of Phosphorene
Andrey A Kistanov, Yongqing Cai, Kun Zhou +2
The poor structural stability of phosphorene in air was commonly ascribed to humidity and oxygen molecules. Recent exfoliation of phosphorene in deoxygenated water promotes the nee…
Mechanical Properties and Failure Behavior of Phosphorene with Grain Boundaries
V. Sorkin, Y. W. Zhang
Using density functional tight-binding method, we studied the effect of grain boundaries on the mechanical properties and failure behavior of phosphorene. We found that the large a…
Theory of substrate-directed heat dissipation for single-layer graphene and other two-dimensional crystals
Zhun-Yong Ong, Yongqing Cai, Gang Zhang
We present a theory of the phononic thermal (Kapitza) resistance at the interface between graphene or another single-layer two-dimensional (2D) crystal (e.g. MoS) and a flat…
