semiconductor nanocrystals News
Trends in Miniaturization
Jan 16, 2015 — Exploiting the unusual optical properties of very small objects, quantum-based technologies are starting to revolutionize lasers, solar cells, communications and more. Smaller is often better, as it frequently can reduce the size and weight of gear...
QDs Form New Platform for Optical Logic
MONTREAL, April 10, 2013 — A new way of controlling light with quantum dots provides a platform for optical logic that could replace electronic transistors with optical ones.
Unique Luminescence Found in Nanocrystals
BERKELEY, Calif., July 6, 2011 — A fundamental principle of photoluminescence known as “Kasha’s rule” was broken by scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory when they created artificial molecules of semiconductor...
QDs Could Revolutionize Computing
QUEBEC, Canada, May 14, 2010 — Physicists at McGill University have developed a system for measuring the energy involved in adding electrons to semiconductor nanocrystals, also known as quantum dots – a technology that may revolutionize computing and other areas of science....
Spanish University Wins Nanotech PV Project
CASTELLÓ, Spain, April 22, 2010 — After responding to a call for proposals, a research group led by Juan Bisquert at Universitat Jaume I of Castelló has won the bid for a scientific and technological research project on new types of solar cells based on nanotechnologies....
Quantum Dots as Building Blocks for High-Security Computers
Oct 1, 2007 — The allure of a quantum computer is powerful. The device, theoretically, could process certain types of information at such an accelerated pace that the classical computers now in use might seem in comparison as antiquated as the manual...
Photopatterning Demonstrated for Nanocrystal-Based LEDs
Apr 1, 2006 — Semiconductor nanocrystals have received attention for their potential in LEDs. Researchers have explored a variety of novel approaches for the assembly of the nanomaterials into a device structure. Now a group from Samsung Advanced Institute of...
Tiny Crystals Promise Big Benefits for Solar Technologies
Jan 25, 2006 — LOS ALAMOS, N.M., Jan. 25, 2006 -- Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a...
Quantum-Dot Films Display Strong Photoluminescence
Oct 1, 2005 — A sol-gel fabrication technique developed at the National Institute of Advanced Industrial Science and Technology in Ikeda, Japan, yields thin films of quantum dots that exhibit photoluminescent efficiencies comparable to that of semiconductor...
Multicolor LEDs Get a Boost from Quantum Dots
Aug 1, 2005 — Much attention in research communities is focused on generating light using semiconductor nanocrystals, also known as quantum dots. One benefit of this method is that emission color can be controlled simply by changing the size of the dots. An...
Electrically Driven Nanocrystal Emitters Proposed
Jul 1, 2004 — Scientists at Los Alamos National Laboratory in Los Alamos, N.M., and at Sandia National Laboratories in Albuquerque, N.M., have reported a scheme that may be suitable for the electrical pumping of displays, light sources, optical amplifiers and...
Quantum Dot Licenses MIT Patents
Sep 3, 2003 — HAYWARD, Calif., Sept. 3 -- Quantum Dot Corp. (QDC) has license three new patents from the Massachusetts Institute of Technology (MIT). QDC will retain exclusive, worldwide license for biological applications for all three patents. The first is US...
