Latest Electron Stories
University of California, Davis, researchers for the first time have looked inside gallium manganese arsenide, a type of material known as a "dilute magnetic semiconductor" that could open up an entirely new class of faster, smaller devices based on an emerging field known as “spintronics.” Materials of this type might be used to read and write digital information not by using the electron’s charge, as is the case with today’s electronic devices, but by using its "spin."...
Berkeley Lab’s lead in laser plasma acceleration research continues with new benchmarks for electron beam quality Part One: Focusing in on beam focus The rapidly evolving technology of laser plasma accelerators (LPAs) – called “table-top accelerators” because their length can be measured in centimeters instead of kilometers – promises a new breed of machines, far less expensive and with far less impact on the land and the environment than today’s conventional accelerators....
Lee Rannals for redOrbit.com – Your Universe Online CSIRO scientist John Lowke thinks he has the mysterious balls of lightning thing figured out, despite himself never witnessing one. Lowke has written a new scientific paper, and has also given the first mathematical solution explaining the birth of ball lightning and how it is capable of passing through glass. Documented sightings of ball lightning have been made across the world for centuries, but no explanation of how it occurs...
Using the world’s fastest laser pulses, which can freeze the ultrafast motion of electrons and atoms, UA physicists have caught the action of molecules breaking apart and electrons getting knocked out of atoms. Their research helps us better understand molecular processes and ultimately be able to control them in many possible applications. In 1878, a now iconic series of photographs instantly solved a long-standing mystery: Does a galloping horse touch the ground at all times? (It...
CHICAGO, Oct. 16, 2012 /PRNewswire/ -- Positron Corporation announced today that the United States Patent and Trademark Office (USPTO) has awarded the Company a patent (U.S. No. 8,269,181) for its original semiconductor detector used in high precision measuring of coordinates and detection of ionization particles. The technology and patent issuance was achieved through collaboration with Dr. Valeri Saveliev of DESY in Hamburg, Germany. Dr. Saveliev's expertise in avalanche pixel...
Lee Rannals for redOrbit.com - Your Universe Online The power of cloaking mechanisms could eventually lead the way for developing more efficient thermoelectric devices and new kinds of electronics. MIT researchers applied the idea of harnessing the cloaking mechanisms developed to shield objects from view, to the movement of electrons. Previous work relied on metamaterials made of artificial materials with unusual properties. The composite structures used for cloaking cause light...
TOKYO, Oct. 11, 2012 /PRNewswire/ -- Tokyo Electron Limited ("Tokyo Electron"; Headquarters: Tokyo; President and CEO: Hiroshi Takenaka) (TSE: 8035) announced earlier today that the tender offer by Tokyo Electron's wholly-owned subsidiary, RB Merger Corp., for all outstanding shares of common stock of FSI International, Inc. ("FSI"; Headquarters: Chaska, Minnesota, USA; Chairman and CEO: Donald Mitchell) (NASDAQ: FSII) for $6.20 in cash for each share of FSI common stock was...
If quantum computers are ever going to perform all those expected feats of code-breaking and number crunching, then their component qubits---tiny ephemeral quantum cells held in a superposition of internal states---will have to be protected from intervention by the outside world. In other words, decoherence, the loss of the qubits’ quantum integrity, has to be postponed. Now theoretical physicists at the Joint Quantum Institute (JQI) and the University of Maryland have done an important...
April Flowers for redOrbit.com - Your Universe Online For the first time since Nobel Prize winner Lev Landau conceived the theoretical existence of quantum levels that determine electron behavior in strong magnetic fields, scientists have directly imaged the phenomenon. The research team, which included scientists from the University of Warwick and Tohoku University, used scanning tunneling spectroscopy – a spatially resolved probe that interacts directly with the electrons – to...
Quantum dots are nanostructures of semiconducting materials that behave a lot like single atoms and are very easy to produce. Given their special properties, researchers see huge potential for quantum dots in technological applications. Before this can happen, however, we need a better understanding of how the electrons “trapped” inside them behave. Dresden physicists have recently observed how electrons in individual quantum dots absorb energy and emit it again as light. Their results...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....
Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
