Borophene is the name for atomically thin, two-dimensional (2D) sheets of boron. Whereas boron is a nonmetallic semiconductor in its bulk form, it becomes a metallic conductor in 2D, even at a thickness of only one atomic layer.
Read moreLithium-ion batteries are ubiquitous in today’s electronic devices such as smart phones and laptops. Even NASA uses rechargeable batteries in many missions to provide electrical power for survival during eclipse periods on solar-powered missions…
Read moreAlthough the first cadmium selenide (CdSe) QD-based light-emitting devices (QLEDs) were developed in 1994, the first perovskite QLEDs were reported only more than 20 years later.
Read moreRadiative cooling is a passive cooling strategy for lowering the temperature of an object without consuming energy or emitting pollution.
Read moreBy varying the energy and dose of tightly-focused electron beams, researchers have demonstrated the ability to both etch away and deposit high-resolution nanoscale patterns on two-dimensional layers of graphene oxide.
Read moreSkin-interfaced, wearable electronics have attracted significant attention due to their unique roles in preventative monitoring, diagnostic confirmation, and convenient therapeutic options.
Read moreAn unusual form of superconductivity, which could help develop powerful quantum computers, has been found at the interface between two thin films by RIKEN physicists (Nature Communications, “Nonreciprocal charge transport at topological insulator/superconductor interface”).
Read moreTwo-dimensional (2D) materials could offer new building blocks for future technologies — but only if scientists can control growth and properties. Strain, caused by “stretching” or “bunching” the atomic structure as a crystal grows, is one way to control these properties.
Read moreA special class of materials known as “Weyl semimetals” have unusual physical properties. In these materials, researchers can separate electrons by their “handedness.” That’s whether the electrons’ magnetic moment is in the same direction as the electrons’ movement or the opposite direction.
This results in a host of unique phenomena that researchers can use to turn infrared light into electricity and develop very fast electronic circuits.
