Kinetic Processes and surfactant design of Group I elements on CZTS (1-1-2-) surface
Kejie Bao, Haolin Liu, Kinfai Tse +3
Cu2ZnSnS4 (CZTS) is a promising thin-film solar-cell material consisted of earth abundant and nontoxic elements. Yet, there exists a fundamental bottle neck that hinders the perfor…
Extremely large magnetoresistance and the complete determination of the Fermi surface topology in the semimetal ScSb
Y. J. Hu, E. I. Paredes Aulestia, K. F. Tse +5
We report the magnetoresistance of ScSb, which is a semimetal with a simple rocksalt-type structure. We found that the magnetoresistance reaches 28000 % at 2 K and 14 T in ou…

Reversible hydrogen incorporation was recently attested [N. Lu, , Nature , 124 (2017)] in , the brownmillerite phase (BM…
Step Stone Effect: A sp anti-bonding Mediated Long-Range Ferromagnetism in Cr-doped Carrier-Free Bi2Te3
Chunkai Chan, Xiaodong Zhang, Yiou Zhang +4
Despite the recent success in the realization of the quantum anomalous Hall effect, the underlying physical mechanism of the long range Ferromagnetism is still unclear. Based on ou…
