New York-based L-3 Communications has appointed James D. Benham to the newly created position of president of the Electron, Microwave and Power Devices Group within the company's Products Group. In this new role, Benham will oversee L-3's electron devices and electron technologies businesses. Since 2000, Benham has been president of L-3's Electron Devices Div. He held the same position at Northrop Grumman and has also been president of Electro-Optical Sensors Inc. L-3 makes intelligence, surveillance and reconnaissance systems and high technology products primarily for communication, guidance and navigation.    . . .    Veeco Instruments Inc. of Woodbury, N.Y., a provider of solutions for nanoscale applications in the data storage, high-brightness LED (HB-LED)/wireless, semiconductor and scientific research markets, announced that Epitech Technology Corp. and Huga Optoelectronics, manufacturers of HB-LEDs, have upgraded their GaNzilla MOCVD (metal organic chemical vapor deposition) systems to Veeco's next-generation reactor technology. Veeco says the new technology allows for higher yields in the production of blue, green and ultraviolet LEDs and blue spectrum lasers, used in the making of GaN-based devices for applications including flat-panel LCD TV backlighting, automotive and specialty architectural lighting.    . . .    European optoelectronic components manufacturer Khatod Optoelectronic of Italy has announced its expansion into the North American market with the naming of Alliance Electronics Corp. of Wilmington, Del., as its master distributor.

A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
