Unusual electric polarization behavior in elemental quasi-2D allotropes of selenium
Dan Liu, Lin Han, Ran Wei +4
We investigate tunable electric polarization and electronic structure of quasi-two-dimensional (quasi-2D) allotropes of selenium, which are formed from their constituent one-dimens…
Efficient Growth and Characterization of One Dimensional Transition Metal Tellurides Inside Carbon Nanotubes
Naoyuki Kanda, Yusuke Nakanishi, Dan Liu +5
Atomically thin one dimensional (1D) van der Waals wires of transition metal monochalocogenides (TMMs) have been anticipated as promising building blocks for integrated nanoelectro…
Effect of Net Charge on the Relative Stability of 2D Boron Allotropes
Dan Liu, David Tomanek
We study the effect of electron doping on the bonding character and stability of two-dimensional (2D) structures of elemental boron, called borophene, which is known to form many s…
Ultralow thermal conductivity of single crystalline porous silicon nanowires
Yunshan Zhao, Lina Yang, Lingyu Kong +10
Porous materials provide a large surface to volume ratio, thereby providing a knob to alter fundamental properties in unprecedented ways. In thermal transport, porous nanomaterials…
Engineering the thermal conductivity along an individual silicon nanowire by selective helium ion irradiation
Yunshan Zhao, Dan Liu, Jie Chen +10
The ability to engineer the thermal conductivity of materials allows us to control the flow of heat and derive novel functionalities such as thermal rectification, thermal switchin…
Two-dimensional phosphorus carbide: Competition between sp2 and sp3 bonding
Jie Guan, Dan Liu, Zhen Zhu +1
We propose previously unknown allotropes of phosphorus carbide (PC) in the stable shape of an atomically thin layer. Different stable geometries, which result from the competition…
