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.

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.

Researchers can optimize the performance of multi-layered, post-fabricated organic photovoltaic devices doped with gold nanoparticles by using combined X-ray diffraction and X-ray fluorescence.

Graphene has been the focal point for many research projects in recent years. It has proved to be one the most diverse materials known to man and recently a team of researchers from Northwestern Engineering have stumbled upon a method of creating graphene ink while trying to discover a new method producing graphene.
