“Valleytronics” – quantum electronics in diamond

deimantas

Diamond is a semiconductor with extreme properties, such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. This makes diamond extreme in the group of wide-bandgap semiconductors, which includes e.g., silicon carbide (SiC) and gallium nitride (GaN).

New nanotechnology breakthrough – “giant surfactants”

Giant Surficant Slide2

University of Akron researchers have developed new materials that function on a nanoscale, which could lead to the creation of lighter laptops, slimmer televisions and crisper smartphone visual displays.

Known as “giant surfactants” — or surface films and liquid solutions — the researchers, led by Stephen Z.D. Cheng, dean of UA’s College of Polymer Science and Polymer Engineering, used a technique known as nanopatterning to combine functioning molecular nanoparticles with polymers to build these novel materials.

3D+2D Television Allows for Simultaneous 3D and 2D Watching

3D Display with no Ghosting

Engineers at UC Santa Cruz have developed a 3D+2D television that that combines both 2D and 3D, allowing viewers with stereo glasses to see three-dimensional images, while viewers without the glasses see a normal two-dimensional image without blurriness.

With existing 3D television displays, viewers must wear stereo glasses to get the effect of seeing images on the screen in three dimensions, while viewers without the glasses see a blurry image. Continue reading “3D+2D Television Allows for Simultaneous 3D and 2D Watching” »

Lithuanian business: no technology design without physicists

v jokuzis 4837

Like every year, during the peak of accessions to the universities, graduates are overloaded with advices: what studies to choose, and what perspectives and disappointments await after selecting certain study fields. As a rule, experts in mass media continue to repeat that social sciences offer the least perspectives, while the most promising areas are considered to be engineering, medicine, and biotechnologies.

A New Way to Trap Light: Phenomenon Could Lead to New Types of Lasers and Sensors

130710141854
There are several ways to "trap" a beam of light -- usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications.

End, begining No. 11

Even devices need eyes and ears

Let’ s say a digital camera or a Smartphone that are filled with various embedded systems remain devices with untapped potential  or a kind of “black box” in the hands of a person who is not aware of certain features?

M. Viliūnas. Your camera has certain functions that help to make good quality photos even without asking your permission.

Entanglement Enhanced Detection of Single Photons

Detection of Single Photons

In a newly published study, physicists from the University of Innsbruck detail a technique to detect the scattering of a single photon on a broad optical transition with high sensitivity, using an entangled state to amplify the tiny momentum kick an ion receives upon scattering a photon.

Metal–oxide–semiconductor field-effect transistor with a vacuum channel

Electrons emitted from the interface of oxide and silicon

With physical barriers limiting further increases in semiconductor electronic efficiency, scientists at the University of Pittsburgh redesigned the structure of the vacuum electronic device, allowing electrons to travel ballistically in a nanometer-scale channel without any collisions or scattering.
