Non-volatile magnetic random-access memories (MRAMs), such as spin-transfer torque
MRAM and next-generation spin–orbit torque MRAM, are emerging as key to enabling low …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

Abstract 2D phosphorene, arsenene, antimonene, and bismuthene, as a fast‐growing family
of 2D monoelemental materials, have attracted enormous interest in the scientific community …

The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

The interplay between topology and correlations can generate a variety of quantum phases,
many of which remain to be explored. Recent advances have identified monolayer WTe2 as …

The experimental manifestation of topological effects in bulk materials is attracting enormous
research interest. However, direct experimental evidence of the effective k-space monopole …

We present the first experimental evidence of a topological phase transition in a
monoelemental quantum spin Hall insulator. Particularly, we show that low-buckled epitaxial …

Chirality or handedness distinguishes an object from its mirror images, such as the spread
thumb, index finger, and middle finger of the right and left hand. In mathematics, it is …

Rapid scaling of semiconductor devices has led to an increase in the number of processor
cores and integrated functionalities onto a single chip to support the growing demands of …

The interface is the device. As the feature size rapidly shrinks, silicon‐based electronic
devices are facing multiple challenges of material performance decrease and interface …
