Unraveling atomic-resolution valence electron energy-loss spectroscopic imaging in a single-crystal CaNb2O6
Sz-Chian Liou, Xiang-Lin Huang, Vladimir P. Oleshko +4
Despite advancements in electron optics and spectrometer design over the past twenty years, atomic-resolution valence-electron energy-loss spectroscopy imaging remains challenging…
Accelerated intermetallic phase amorphization in a Mg-based high-entropy alloy powder
Prince Sharma, Purvam Mehulkumar Gandhi, Kerri-Lee Chintersingh +4
We describe a novel mechanism for the synthesis of a stable high-entropy alloy powder from an otherwise immiscible Mg-Ti rich metallic mixture by employing high-energy mechanical m…
Synergistically creating sulfur vacancies in semimetal-supported amorphous MoS2 for efficient hydrogen evolution
Guowei Li, Chenguang Fu, Jiquan Wu +14
The presence of elemental vacancies in materials is inevitable according to statistical thermodynamics, which will decide the chemical and physical properties of the investigated s…
Dynamic surface electronic reconstruction as symmetry-protected topological orders in topological insulator Bi2Se3
G. J. Shu, S. C. Liou, S. K. Karna +3
Layered narrow band gap semiconductor Bi2Se3 is composed of heavy elements with strong spin-orbital coupling (SOC), which has been identified both as a good candidate of thermoelec…
Graphene-like conjugated pi-bond system in Pb1-xSnxSe
G. J. Shu, S. C. Liou, S. Karna +4
Following the identification of the pi bond in graphene, in this work, a pi bond constructed through side-to-side overlap of half-filled 6pz orbitals was observed in a non-carbon c…
pi-bonds in graphene and surface of topological insulator Bi2Se3
G. J. Shu, S. C. Liou, F. C. Chou
Chemical bond analysis for the topological insulator (TI) Bi2Se3 following valence bond theory and VSEPR rule is proposed and compared to that of graphene. The existence of pi-bond…
