Photo-induced change of refractive index and transparency in Bi2Te3 films
Zengji Yue, Qinjun Chen, Amit Sahu +2
We report on an 800 nm femtosecond laser beam induced giant refractive index modulation and enhancement of near-infrared transparency in topological insulator material Bi2Te3 thin…
Interactions between Coherent Twin Boundaries and Phase Transition of Iron under Dynamic Loading and Unloading
Kun Wang, Jun Chena, Xueyang Zhang +1
Under high pressures, phase transition, as well as deformation twins, are constantly reported in many BCC metals, whose interactions are of fundamental importance to understand str…
Observation of topological edge states of sound at a momentum away from the high-symmetry point
Bai-Zhan Xia, Sheng-Jie Zheng, Ning Chen +5
Topologically protected one-way transportation of sound, mimicking the topological properties of the condensed matter, has received greatly attentions. Thus far, the topological ph…
Hydrogenation Facilitates Proton Transfer Through Two-Dimensional Honeycomb Crystals
Yexin Feng, Ji Chen, Wei Fang +3
Recent experiments have triggered a debate about the ability of protons to transfer through individual layers of graphene and hexagonal boron nitride (h-BN). However, calculations…
Topological phononic insulator with robustly pseudospin-dependent transport
Bai-Zhan Xia, Ting-Ting Liu, Hong-Qing Dai +5
Topological phononic states, facilitating acoustic unique transports immunizing to defects and disorders, have significantly revolutionized our scientific cognition of acoustic wav…
