Two-dimensional (2D) materials exhibit a wide range of atomic structures, compositions, and
associated versatility of properties. Furthermore, for a given composition, a variety of …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

We explore the formation of single bilayer Sb (111) ultrathin film (Antimonene) on Bi 2 Te 3
and Sb 2 Te 3 substrates for the first time, which is theoretically predicated to be a robust …

Topological quantum materials with layered heterostructure hold great promise for exhibiting
low thermal conductivity. Homologous (Bi2) m (Bi2Se3) n (m, n: integers) series hosts …

Abstract New three-dimensional (3D) topological phases can emerge in superlattices
containing constituents of known two-dimensional topologies. Here we demonstrate that …

The stability of the surface of vacuum-cleaved topological insulator Bi2Se3 single crystals is
investigated with high-resolution synchrotron-based photoelectron spectroscopy. While the …

Meeting of non-trivial topology with magnetism results in novel phases of matter, such as
quantum anomalous Hall (QAH) or axion insulator phases. Even more exotic states with …

Zintl compounds have been extensively studied for their outstanding thermoelectric
properties, but their electronic structure remains largely unexplored. Here, we present a …

The electronic topology of Bi 4 Te 3, composed of alternating Bi 2 and Bi 2 Te 3 layers, is
investigated by density functional theory and angle-resolved photoemission spectroscopy …

The topological insulator/normal insulator (TI/NI) superlattices (SLs) with multiple Dirac
channels are predicted to offer great opportunity to design novel materials and investigate …
