The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

Topological insulators (TIs) provide intriguing prospects for the future of spintronics due to
their large spin–orbit coupling and dissipationless, counter‐propagating conduction …

Quantum spin Hall materials hold the promise of revolutionary devices with dissipationless
spin currents but have required cryogenic temperatures owing to small energy gaps. Here …

A two-dimensional topological insulator (2DTI) is guaranteed to have a helical one-
dimensional edge mode,,,,,,,,,, in which spin is locked to momentum, producing the quantum …

Topological insulators represent a new quantum state of matter which is characterized by
peculiar edge or surface states that show up due to a topological character of the bulk wave …

Coulomb drag is a transport phenomenon whereby long-range Coulomb interaction
between charge carriers in two closely spaced but electrically isolated conductors induces a …

The quantum spin Hall (QSH) state is a state of matter characterized by a non-trivial topology
of its band structure, and associated conducting edge channels,,,,. The QSH state was …

We study the influence of electron puddles created by do** of a 2D topological insulator
on its helical edge conductance. A single puddle is modeled by a quantum dot tunnel …

We propose to engineer time-reversal-invariant topological insulators in two-dimensional
crystals of transition-metal dichalcogenides (TMDCs). We note that, at low do** …

Time-reversal symmetry prohibits elastic backscattering of electrons propagating within a
helical edge of a two-dimensional topological insulator. However, small band gaps in these …
