Shuji Nakamura
is a Japanese electronic engineer, inventor of the blue LED, a major breakthrough in lighting technology, and recipient of the Nobel Prize in Physics in 2014. Nakamura specializes in the field of semiconductor technology, and he is a professor of materials science at the College of Engineering of the University of California, Santa Barbara (UCSB). Together with Isamu Akasaki and Hiroshi Amano, Nakamura received the 2014 Nobel Prize for Physics "for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources". In 2015, his input into the commercialization and development of energy-efficient white LED lighting technology was recognized by the Global Energy Prize. In 2021, Nakamura, along with Akasaki, Nick Holonyak, M. George Craford, and Russell D. Dupuis, were awarded the Queen Elizabeth Prize for Engineering "for the creation and development of LED lighting, which forms the basis of all solid-state lighting tec ...

Ikata, Ehime
is a small peninsula town located in Nishiuwa District, Ehime Prefecture, Japan. , the town had an estimated population of 8,497 in 15638 households and a population density of 90 persons per km2. The total area of the town is Following a recent merger with the neighboring towns of Misaki and Seto, the town now spans the mountainous Sadamisaki Peninsula, the narrowest peninsula in Japan and the westernmost point on the island of Shikoku. This unique geography has greatly influenced Ikata's growth. On the one hand, it has presented significant challenges to urban development that were not overcome until recently in the town's long history. On the other, the peninsula is what gives the town its beautiful mountain and ocean scenery which, bolstered by significant investments in infrastructure and tourist facilities, has formed the basis for a burgeoning tourism industry. In addition to the beauty of its rugged, natural landscape, Ikata has long been known for fishing and mika ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extrinsic Semiconductor
In science and engineering, an intrinsic property is a property of a specified subject that exists itself or within the subject. An extrinsic property is not essential or inherent to the subject that is being characterized. For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that depends on the strength of the gravitational field in which the object is placed. Applications in science and engineering In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material. Extrinsic properties are differentiated as being dependent on the presence of avoidable chemical contaminants or structural defects. In biology, intrinsic effects originate from inside an organism or cell, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue
Blue is one of the three primary colours in the RYB color model, RYB colour model (traditional colour theory), as well as in the RGB color model, RGB (additive) colour model. It lies between Violet (color), violet and cyan on the optical spectrum, spectrum of visible light. The term ''blue'' generally describes colours perceived by humans observing light with a dominant wavelength that's between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; Azure (color), azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering#Cause of the blue colour of the sky, Rayleigh scattering. An optical effect called the Tyndall effect explains Eye color#Blue, blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronic Engineering
Electronic engineering is a sub-discipline of electrical engineering that emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow. Previously electrical engineering only used passive devices such as mechanical switches, resistors, inductors, and capacitors. It covers fields such as analog electronics, digital electronics, consumer electronics, embedded systems and power electronics. It is also involved in many related fields, for example solid-state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, electric power control, photonics and robotics. The Institute of Electrical and Electronics Engineers (IEEE) is one of the most important professional bodies for electronics engineers in the US; the equivalent body in the UK is the Institution of Engin ...
