quantum dot News
Computers Use Quantum Photonics
STANFORD, Calif., May 19, 2008 -- What was once considered more theoretical than practical, computers based on the powerful properties of quantum mechanics now have the potential to revolutionize information technology and security. Engineers and physicists from Stanford and the...
Fano Effect Seen Using Quantum Dot
MUNICH, Germany, Jan. 17, 2008 -- An international team of researchers has revealed a previously unseen phenomenon known as the Fano effect by using an artificial nanostructure -- a quantum dot (QD) -- instead of an atom. The work could allow the exploration of new frontiers in...
Quantum Dots as Tiny Thermometers
Nov 1, 2007 — As technology gets smaller and smaller, it is becoming increasingly difficult to take accurate temperature readings in systems that are measured in the micro- and nanometer ranges. Researchers from the University of California, Berkeley, and from...
Device Counts Single Photons
GAITHERSBURG, Md., Oct. 16, 2007 -- A new transistor uses quantum dots to help it count individual photons (the smallest particles of light). Because it could be easily integrated into electronics and may operate at higher temperatures than other single-photon detectors, it offers...
Purdue Gets Nano Grant
WEST LAFAYETTE, Ind., Sept. 20, 2007 -- Purdue University's Network for Computational Nanotechnology has received a five-year, $18.25 million grant from the National Science Foundation (NSF) to support the US National Nanotechnology Initiative with expanded capabilities and services for...
Are Quantum Dots on the Brink of Their Big Break?
May 1, 2007 — The period at the end of this sentence would be colossal next to a quantum dot — like a flea clinging to a good-size dog. As many as a million quantum dots could perhaps fit within the narrow confines of this circle: o. In other words, quantum...
Progress Made Toward Single-Qdot Laser
GAITHERSBURG, Md., April 16, 2007 -- A micrometer-sized solid-state laser has been built that, while not powered by a single quantum dot, effectively demonstrates that just one dot can play a dominant role in the device's performance. These highly efficient optical devices could one...
A Single Dot Marks the Spot for Nanowire LEDs
Apr 1, 2007 — From wires nanometers in size, an industry hopes that mighty lights will grow. That goal — as well as the ability to perform quantum optics experiments — has gotten a boost, thanks to researchers from the Kavli Institute of Nanoscience at Delft...
Imaging Focus of BiOS at Photonics West
SAN JOSE, Calif., Jan. 23, 2007 -- Photonics West 2007 opened Saturday amid a number of photonics-related advances, both commercially and in development, that are creating a great deal of excitement. BiOS 2007, the International Biomedical Optics Symposium, kicked off Photonics West...

Nanoparticles Viewed in 3-D
DAVIS, Calif., Nov. 28, 2006 -- A new x-ray microscope has been devised that can, for the first time, examine nanoparticles -- materials smaller in scale than one billionth of a meter -- in three dimensions. The device could be used to make better materials for electronics, optics...
Researchers Seek to Integrate THz Detectors and Electronics
BUFFALO, N.Y., Oct. 11, 2006 -- Sensors and detectors that work in the terahertz range show promise in applications ranging from precise identification of concealed weapons to the ability to distinguish between different tissue types for disease screening, but signals in that...
Cryogenic Laser Photolithography Finds Quantum Dot Registration
Jul 1, 2006 — In quantum dot information processing, it is critical to be able to register the position of a single quantum dot with respect to the antinode of a defect (missing hole) in a photonic crystal to create strong coupling and cavity quantum...
QUANTUM DOT HISTORY
Feb 1, 2006 — Evident Technologies Inc. has unveiled “The Quantum Dot History Project,” an online living history of early work in the field of quantum dot technology. Providing a representative overview of key research and researchers mainly from 1960 to 1996,...
Quantum Dot Single-Photon Detector Is Studied
Mar 1, 2005 — Scientists at Toshiba Research Europe Ltd. and at Cambridge University, both in Cambridge, UK, have demonstrated that single photons may be detected in a quantum dot device by monitoring changes in the resonant tunneling current through a...
Daily News Briefs
Dec 6, 2004 — Actuality Systems Inc., a Burlington, Mass., developer of spatial 3-D visualization technology, has installed at Perspecta spatial 3-D system in the Department of Radiation Oncology at Rush University Medical Center in Chicago. The system will be...
Quantum Dot Awarded NIST Grant
Sep 29, 2004 — HAYWARD, Calif., Sept. 29 --Quantum Dot Corp. (QDC) announced it was awarded a $2 million grant from the National Institute of Standards and Technology (NIST), under its Advanced Technology Program, to develop clinical-grade quantum dots with...
Daily News Briefs
Sep 8, 2004 — The IEEE-Communications Society, the IEEE-Lasers & Electro-Optics Society and the Optical Society of America have announced the upcoming call-for-papers deadline for the Optical Fiber Communication Conference and Exposition and the National Fiber...
Daily News Briefs
Apr 12, 2004 — Toshiba Corp. announced last week that it plans to release a flat panel TV that it has been developing with Canon Inc. President Tadashi Okamura said Toshiba aims to make imaging-device-related businesses a new core revenue source. The television...
Quantum Dots Capture Movies of 'Talking' Cells
Mar 1, 2004 — HAYWARD, Calif., March 1 -- Researchers at the Max Planck Institute for Biophysical Chemistry in Goettingen, Germany, have used a new nano-sized imaging tool to capture the first-ever movies of cells transmitting the messages that control genes. The...
Quantum Dots Reveal Minute Details of Brain Chemistry
Oct 20, 2003 — HAYWARD, Calif., Oct. 20 --French researchers have used a new imaging tool, the size of individual molecules, to reveal more clearly than ever before the workings of the human nervous system -- including processes that may eventually provide clues...
Daily News Briefs
Aug 11, 2003 — Quantum Dot Corp. (QDC) SC BioSciences Corp., Matsushita Electric Industrial Co. Ltd. (MEI) and Matsushita Kotobuki Electronics (MKE) announced they have reached an agreement to develop, manufacture and market life science detection products. The...
