Facebook X LinkedIn Email
TOKYO, April 21, 2006 -- Communications solutions provider Fujitsu Ltd. and trading house Mitsui & Co. Ltd. announced that they will cooperate to develop and manufacture quantum dot lasers and optical devices through their new joint business, QD Laser Inc. (QDL). Quantum dots are semiconductor particles that are a single nanometer (one billionth of a meter) in size. Quantum dots and technology using quantum dots were developed through an academic-industrial research collaboration by Fujitsu Ltd., Fujitsu Laboratories and Professor Yasuhiko Arakawa's laboratory at the University of Tokyo, the companies said in a...Read full article

    quantum dots
    A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
