Physics research groups have generated free electrons from organic semiconductors when combined with a single atomic layer of molybdenum disulfide, a recently discovered 2D semiconductor.

Imagine printing electronic devices using a simple inkjet printer – or even painting a solar panel onto the wall of a building. Such technology would slash the cost of manufacturing electronic devices and enable new ways to integrate them into our everyday lives. Over the last two decades, a type of material called organic semiconductors, made out of molecules or polymers, has been developed for such purposes...

Two-qudit gate on a photonic platform achieves massive entangled quantum state. Researchers have built what could be a quantum version of a transistor – with qudits.

Quantum information processing promises to be much faster and more secure than what today’s supercomputers can achieve, but doesn’t exist yet because its building blocks, qubits, are notoriously unstable.

Purdue University researchers are among the first to build a gate – what could be a quantum version of a transistor, used in today’s computers for processing information – with qudits...

A team of researchers has developed tiny 10-gram robots that are inspired by ants: they can communicate with each other, assign roles among themselves and complete complex tasks together. These reconfigurable robots are simple in structure, yet they can jump and crawl to explore uneven surfaces. Individually, ants have only so much strength and intelligence. However, as a colony, they can use complex strategies to complete sophisticated tasks and evade larger predators.

At EPFL, robotics researchers in Professor Jamie Paik’s Laboratory have reproduced this phenomenon, developing tiny robots that display minimal physical intelligence on an individual level but t...

Team identifies dark trions as the next carrier of quantum information. Move aside, electrons; it’s time to make way for the trion. A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor – ultraclean single-layer tungsten diselenide (WSe2) – a feat that could increase the capacity and alter the form of information transmission.

In a semiconductor, such as WSe2, a trion is a quantum bound state of three charged particles. A negative trion contains two electrons and one hole; a positive trion contains two holes and one electron...
