Phonon renormalization induced by electric field in ferroelectric P(VDF-TrFE) nanofibers
Lan Dong, Qing Xi, Jun Zhou +2
We report phonon renormalization induced by an external electric field E in ferroelectric poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] nanofibers through measuring the…
Off-center Rattling Triggers High-Temperature Thermal Transport in Thermoelectric lathrates: Non-Perturbative Approach
Qing Xi, Zhongwei Zhang, Tsuneyoshi Nakayama +3
Lattice thermal conductivities of type-I clathrates encapsulating "off-center" guest atoms behave in a way that is sharply different from those of conventional crystals…
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…
Phononic thermal properties of two-dimensional materials
Xiaokun Gu, Yujie Wei, Xiaobo Yin +2
Following the emergence of many novel two-dimensional (2-D) materials beyond graphene, interest has grown in exploring implications for fundamental physics and practical applicatio…
Layer thickness-dependent phonon properties and thermal conductivity of MoS2
Xiaokun Gu, Baowen Li, Ronggui Yang
For conventional materials, the thermal conductivity of thin film is usually suppressed when the thickness decreases due to phonon-boundary scattering. However, this is not necessa…
