In situ modification of delafossite type PdCoO2 bulk single crystal for reversible hydrogen sorption and fast hydrogen evolution
Guowei Li, Seunghyun Khim, Celesta S. Chang +11
The observation of extraordinarily high conductivity in delafossite-type PdCoO2 is of great current interest, and there is some evidence that electrons behave like a fluid when flo…
Laser floating zone growth of SrVO single crystals
Tanya Berry, Shannon Bernier, Gudrun Auffermann +2
The perovskite SrVO is of interest for a variety of applications due to its simple metallic character and stability in reducing environments. Here we report the preparation of…
Surface states in bulk single crystal of topological semimetal CoSnS towards water oxidation
Guowei Li, Qiunan Xu, Wujun Shi +16
The band inversion in topological phase matters bring exotic physical properties such as the emergence of a topologically protected surface states. They strongly influence the surf…
Large Nernst Power Factor over a Broad Temperature Range in Polycrystalline Weyl Semimetal NbP
Chenguang Fu, Satya N. Guin, Sarah J. Watzman +10
The discovery of topological materials has provided new opportunities to exploit advanced materials for heat-to-electricity energy conversion as they share many common characterist…
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…
Growth and transport properties of Mg3X2 (X = Sb, Bi) single crystals
Jiazhan Xin, Guowei Li, Gudrun Auffermann +7
The discovery of high thermoelectric performance in n-type polycrystalline Mg3(Sb,Bi)2 based Zintl compounds has ignited intensive research interest. However, some fundamental ques…
