How quantum dots can 'talk' to each other

So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range. The optical and electrical properties can be controlled ...

Diamonds are not just for jewelry anymore

When it comes to the semiconductor industry, silicon has reigned as king in the electronics field, but it is coming to the end of its physical limits.

Producing materials to help break the electronics scaling limit

Ph.D. candidate Saravana Balaji Basuvalingam at the TU/e Department of Applied Physics has developed a new approach to grow, in a controlled and effective way, a library of so-called "TMC materials" with various properties ...

Bending light to engineer improved optical devices and circuits

Rainbows are formed when light bends—or refracts—as it enters and exits a water droplet. The amount that the light bends depends on the color of the light, resulting in white light being separated into a beautiful spectrum ...

Resonant tunneling diode oscillators for terahertz-wave detection

A semiconductor device that is promising for both generating and detecting terahertz radiation has been demonstrated by physicists at RIKEN. This may aid the development of high-performance integrated solutions for terahertz ...

A theoretical boost to nano-scale devices

Semiconductor companies are struggling to develop devices that are mere nanometers in size, and much of the challenge lies in being able to more accurately describe the underlying physics at that nano-scale. But a new computational ...
