Abstract van der Waals epitaxy (VDWE) is an ideal method for growing 2D materials and
topological insulators (TIs) onto a variety of substrates for heterostructure and integrated …

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 …

Recent demonstrations of magnetization switching induced by in-plane current in heavy
metal/ferromagnetic heterostructures (HMFHs) have drawn great attention to spin torques …

Topological insulators (TIs) have an insulating bulk but a metallic surface. In the simplest
case, the surface electronic structure of a three-dimensional (3D) TI is described by a single …

Infrared detection at optical communication wavelength is of great significance because of
their diverse commercial and military communication applications. The layered Bi2Se3 with …

Electric-field manipulation of magnetic order has proved of both fundamental and
technological importance in spintronic devices. So far, electric-field control of …

The massless Dirac fermions residing on the surface of three-dimensional topological
insulators are protected from backscattering and cannot be localized by disorder, but such …

An intriguing property of a three-dimensional (3D) topological insulator (TI) is the existence
of surface states with spin-momentum locking, which offers a new frontier of exploration in …

Strong spin–orbit interaction and time-reversal symmetry in topological insulators enable the
spin-momentum locking for the helical surface states. To date, however, there has been little …

Abstract Infrared (IR) detection at 1300–1650 nm (optical communication waveband) is of
great significance due to its wide range of applications in commerce and military. Three …
