Gallium Nitride
Gallium nitride () is a binary III/ V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure. Its wide band gap of 3.4  eV affords it special properties for applications in optoelectronics, high-power and high-frequency devices. For example, GaN is the substrate that makes violet (405 nm) laser diodes possible, without requiring nonlinear optical frequency doubling. Its sensitivity to ionizing radiation is low (like other group III nitrides), making it a suitable material for solar cell arrays for satellites. Military and space applications could also benefit as devices have shown stability in high-radiation environments. Because GaN transistors can operate at much higher temperatures and work at much higher voltages than gallium arsenide (GaAs) transistors, they make ideal power amplifiers at microwave frequencies. In addition, GaN offers promising c ...

Manufacturing Companies Established In 1999
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final produc ...

Aluminium Gallium Indium Phosphide
Aluminium gallium indium phosphide (, also AlInGaP, InGaAlP, etc.) is a semiconductor material that provides a platform for the development of multi-junction photovoltaics and optoelectronic devices. It has a direct bandgap ranging from ultraviolet to infrared photon energies. AlGaInP is used in heterostructures for high-brightness red, orange, green, and yellow light-emitting diodes. It is also used to make diode lasers. Preparation AlGaInP is typically grown by heteroepitaxy on gallium arsenide or gallium phosphide substrates in order to form a quantum well structure that can be fabricated into different devices. Properties The direct bandgap of AlGaInP encompasses the energy range of visible light (1.7 eV - 3.1 eV). By selecting a specific composition of AlGaInP, the bandgap can be selected to correspond to the energy of a specific wavelength of visible light. For instance, this can be used to obtain LEDs that emit red, orange, or yellow light. Like most other ...

Times Square Ball
The Times Square Ball is a time ball located in New York City's Times Square. Located on the roof of One Times Square, the ball is a prominent part of a New Year's Eve celebration in Times Square commonly referred to as the ball drop, where the ball descends down a specially designed flagpole, beginning at 11:59:00 p.m. ET, and resting at midnight to signal the start of the new year. In recent years, the ball drop has been preceded by live entertainment, including performances by musicians. The event was first organized by Adolph Ochs, owner of ''The New York Times'', as an extension to a series of New Year's Eve fireworks displays he held at the building to promote its status as the new headquarters of the ''Times'', while the ball itself was designed by Artkraft Strauss. First held on December 31, 1907, to welcome 1908, the ball drop has been held annually since, except in 1942 and 1943 in observance of wartime blackouts. The event is currently organized by the Ti ...
