Restoring Pristine Bi2Se3 Surface with an Effective Se Decapping Process
Jixia Dai, Wenbo Wang, Matthew Brahlek +4
High quality thin films of topological insulators (TI) such as Bi2Se3 have been successfully synthesized by molecular beam epitaxy (MBE). Although the surface of MBE films can be p…
Hierarchical stripe phases in IrTe2 driven by competition between Ir dimerization and Te bonding
Jixia Dai, Kristjan Haule, J. J. Yang +3
Layered 5d transition metal dichalcogenide (TMD) IrTe2 is distinguished from the traditional TMDs (such as NbSe2) by the existence of multiple CDW-like stripe phases and supercondu…
Transferring MBE-grown topological insulator films to arbitrary substrates and Metal-insulator transition via Dirac gap
Namrata Bansal, Myung Rae Cho, Matthew Brahlek +6
Mechanical exfoliation of bulk crystals has been widely used to obtain thin topological insulator (TI) flakes for device fabrication. However, such a process produces only micro-si…
