New Quasi-Particle Found:

Mysterious Quantum ‘Dropletons’ Form Inside Semiconductors Shot With Lasers

by Adam Mann

By shooting a semiconductor with ultra-fast laser pulses, scientists have discovered a new quasiparticle that behaves like a drop of liquid. They describe it as a quantum droplet, and named it “dropleton.”

These things were not predicted under any theory and surprised scientists when they appeared unexpectedly in extremely low temperature semiconductor experiments. They have properties unlike anything seen before.

“At first we scratched our heads,” said physicist Steven Cundiff of the University of Colorado and National Institute of Standards and Technology in Boulder, one of the authors of a paper appearing today in Nature. “But then we came up with this idea that what we were seeing was this new thing we’re calling a quantum droplet.”

Now before you start asking questions like, “What?” and “Huh?” we probably need to break things down a little here…

Self-assembling Material May Produce Flat Semiconductors

Researchers around the world have been working to harness the unusual properties of graphene, a two-dimensional sheet of carbon atoms. But graphene lacks one important characteristic that would make it even more useful: a property called a bandgap, which is essential for making devices such as computer chips and solar cells.

Now, researchers at MIT and Harvard Univ. have found a two-dimensional material whose properties are very similar to graphene, but with some distinct advantages — including the fact that this material naturally has a usable bandgap.

20Hz observes a geo-magnetic storm occurring in the Earth’s upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception.

Ampere to get rational redefinition

Single-electron flow measured in bid to overhaul SI base unit.

Physicists have tracked electrons crossing a semiconductor chip one at a time — an experiment that should at last enable a rational definition of the ampere, the unit of electrical current.

At present, an ampere is defined as the amount of charge flowing per second through two infinitely long wires one metre apart, such that the wires attract each other with a force of 2 × 10−7 newtons per metre of length. That definition, adopted in 1948 and based on a thought experiment that can at best be approximated in the laboratory, is clumsy — almost as much of an embarrassment as the definition of the kilogram, which relies on the fluctuating mass of a 125-year-old platinum-and-iridium cylinder stored at the International Bureau of Weights and Measures (BIPM) in Paris.

Quantum Dot Acts as Semiconductor

If you could peek at the inner workings of a computer processor you would see billions of transistors switching back and forth between two states. In optical communications, information from the switches can be encoded onto light, which then travels long distances through glass fiber. Researchers at the Joint Quantum Institute and the Department of Electrical and Computer Engineering are working to harness the quantum nature of light and semiconductors to expand the capabilities of computers in remarkable ways.

All computers, even the future quantum versions, use logic operations or “gates,” which are the fundamental building blocks of computational processes. JQI scientists, led by Prof. Edo Waks, have performed an ultrafast logic gate on a photon, using a semiconductor quantum dot. This research is described in the Advance Online Publication of Nature Photonics.

Researchers at the Norwegian University of Science and Technology (NTNU) have patented and are commercializing GaAs nanowires grown on graphene, a hybrid material with competitive properties. Semiconductors grown on graphene are expected to become the basis for new types of device systems, and could fundamentally change the semiconductor industry. The technology underpinning their approach has recently been described in a publication in the American research journal Nano Letters.

A new type of transistor shaped like a Christmas tree has arrived just in time for the holidays, but the prototype won’t be nestled under the tree along with the other gifts.

"It’s a preview of things to come in the semiconductor industry," said Peide "Peter" Ye, a professor of electrical and computer engineering at Purdue University.

Researchers from Purdue and Harvard universities created the transistor, which is made from a material that could replace silicon within a decade. Each transistor contains three tiny nanowires made not of silicon, like conventional transistors, but from a material called indium-gallium-arsenide. The three nanowires are progressively smaller, yielding a tapered cross section resembling a Christmas tree.

The research builds on previous work in which the team created a 3-D structure instead of conventional flat transistors. The approach could enable engineers to build faster, more compact and efficient integrated circuits and lighter laptops that generate less heat than today’s.

New findings show how to improve the device performance by linking the transistors vertically in parallel.

Organic Semiconductor May Enable Flexible Electronics

The sense of touch is something we take for granted. The sensitive nerves in our finger tips generate a flow of information to our brains that enables us to do things that require extraordinary precision. Reaching out for an object in the darkness, we are able to tell in a split second what we’re touching and how to respond. Artificial skin with the ability to process information – such as texture and temperature – has long been the holy grail of researchers working on the next generation of electronics. Artificial skin, which has potential in areas such as robotics, and other products are now within our grasp as the result of recent research into the exciting field of plastic electronics.
