Ternary Hypervalent Silicon Hydrides via Lithium at High Pressure
Tianxiao Liang, Zihan Zhang, Xiaolei Feng +4
Hydrogen is rarely observed as ligand in hypervalent species, however, we find that high-pressure hydrogenation may stabilise hypervalent hydrogen-rich materials. Focussing on tern…
A short-range metastable defect in the double layer ice
Zhiyuan Zhang, Yu Zhu, Le Jin +4
Although the phase of water has extensively investigated whether there exists a defect distorting only locally the structure still under debate. Here we report a localized 5775 def…
Topological phase transition and phonon-space Dirac topology surfaces in ZrTe
Niraj Aryal, Xilian Jin, Q. Li +2
We use first-principles methods to reveal that in ZrTe, a layered van der Waals material like graphite, atomic displacements corresponding to five of the six zone-center A…
Concurrent probing of electron-lattice dephasing induced by photoexcitation in 1T-TaSeTe using ultrafast electron diffraction
Jun Li, Junjie Li, Kai Sun +12
It has been technically challenging to concurrently probe the electrons and the lattices in materials during non-equilibrium processes, allowing their correlations to be determined…
Characterization of rattling in relation to thermal conductivity: ordered half-Heusler semiconductors
Zhenzhen Feng, Yuhao Fu, Yongsheng Zhang +1
The factors that affect the thermal conductivity of semiconductors is a topic of great scientific interest, especially in relation to thermoelectrics. Key developments have been th…
