Large bandgap quantum anomalous hall insulator in a designer ferromagnet-topological insulator-ferromagnet heterostructure
Qile Li, Chi Xuan Trang, Weikang Wu +5
Combining magnetism and nontrivial band topology gives rise to quantum anomalous Hall (QAH) insulators and exotic quantum phases such as the QAH effect where current flows without…
Progress in epitaxial thin-film Na3Bi as a topological electronic material
I. Di Bernardo, J. Hellerstedt, C. Liu +8
Na3Bi was the first experimentally verified topological Dirac semimetal (TDS), and is a 3D analogue of graphene hosting relativistic Dirac fermions. Its unconventional momentum-ene…
Experimental and Theoretical Electronic Structure and Symmetry Effects in Ultrathin NbSe2 Films
Cai-Zhi Xu, Xiaoxiong Wang, Peng Chen +6
Layered quasi-two-dimensional transition metal dichalcogenides (TMDCs), which can be readily made in ultrathin films, offer excellent opportunities for studying how dimensionality…
Emergence of charge density waves and a pseudogap in single-layer TiTe2
P. Chen, Woei Wu Pai, Y. -H. Chan +8
Two-dimensional materials constitute a promising platform for developing nanoscale devices and systems. Their physical properties can be very different from those of the correspond…
Observation of charge density wave order in 1D mirror twin boundaries of single-layer MoSe2
Sara Barja, Sebastian Wickenburg, Zhen-Fei Liu +13
Properties of two-dimensional transition metal dichalcogenides are highly sensitive to the presence of defects in the crystal structure. A detailed understanding of defect structur…
Characterization of collective ground states in single-layer NbSe2
Miguel M. Ugeda, Aaron J. Bradley, Yi Zhang +14
Layered transition metal dichalcogenides (TMDs) are ideal systems for exploring the effects of dimensionality on correlated electronic phases such as charge density wave (CDW) orde…
