Kaloni, T. P., Kou, L., Frauenheim, T., & Schwingenschlögl, U. (2014) Quantum spin Hall states in graphene interacting with WS2 or WSe2. Applied Physics Letters, 105(23), Article Number-233112.

In the framework of first-principles calculations, we investigate the structural and electronic properties of graphene in contact with as well as sandwiched between WS2 and WSe2 monolayers. We report the modification of the band characteristics due to the interaction at the interface and demonstrate that the presence of the dichalcogenide results in quantum spin Hall states in the absence of a magnetic field.

9 citations in Scopus
Search Google Scholar™
12 citations in Web of Science®

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
