High-precision control of printed electronics

Printed electronic transistor circuits and displays, in which the colour of individual pixels can be changed, are two of many applications of ground-breaking research at the Laboratory of Organic Electronics, Linköping University. New groundbreaking results on these topics have been published in the scientific journal Science Advances. The researchers in organic electronics have a favourite

Quantum thermometer or optical refrigerator?

In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest principles of quantum physics, these optomechanical systems can act as inherently accurate thermometers, or conversely, as a

Designing new materials from ‘small’ data

Finding new functional materials is always tricky. But searching for very specific properties among a relatively small family of known materials is even more difficult. But a team from Northwestern Engineering and Los Alamos National Laboratory found a workaround. The group developed a novel workflow combining machine learning and density functional theory calculations to create

Creating atomic scale nanoribbons

Silicon crystals are the semiconductors most commonly used to make transistors, which are critical electronic components used to carry out logic operations in computing. However, as faster and more powerful processors are created, silicon has reached a performance limit: the faster it conducts electricity, the hotter it gets, leading to overheating. Graphene, made of a
