Although 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.

Skin-interfaced, wearable electronics have attracted significant attention due to their unique roles in preventative monitoring, diagnostic confirmation, and convenient therapeutic options.

Scientists from the Skoltech Center for Energy Science and Technology (CEST) and the Institute for Problems of Chemical Physics of Russian Academy of Sciences have developed a novel approach for preparing thin semiconductor fullerene films.

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics developed a thickness-controlled black phosphorous tunnel field-effect transistor (TFET) that shows 10-times lower switching power consumption as well as 10,000-times lower standby power consumption than conventional complementary metal-oxide-semiconductor (CMOS) transistors.

Scientists from the Skoltech Center for Energy Science and Technology (CEST) and the Institute for Problems of Chemical Physics of Russian Academy of Sciences have developed a novel approach for preparing thin semiconductor fullerene films. The method enables fabrication of organic electronics without using toxic organic solvents and costly vacuum technologies, thus reducing the environmental risks and making organic electronics more accessible.

Gas and water permeation barrier films play a vital part in applications ranging from food and pharmaceutical packaging to electronic devices. Two-dimensional (2D) materials, like graphene, are highly promising as ultra-high barrier materials, and their atomic thinness, mechanical stability, optical transparency and thermal properties offers many new possibilities and device form factors.

Nowadays, with all the places digital displays can be found, evidence indicates that it may not be that hip to be square. Displays that push the boundaries of the conventional rectangular, flat-panel design permit extremely organic incorporation of display features into shapes and sizes that are a far better fit with their use and context. Non-rectangular displays are also known as freeform displays (sometimes “free form” or “free-form”), which denotes their bespoke shapes and alludes to the design freedom that they bestow to device manufacturers.

Researchers from Chemnitz University of Technology have printed flexible and lightweight polymer speakers.
