Semiconductors have served as choice materials for many electronic and optical devices because of their physical properties. Commercial solar cells, computer chips and other semiconductor technologies...
Power and Electrical Engineering | Read moreDiscovery of nonblinking semiconductor nanocrystals advances their applications
This discovery recently announced by scientists at the Naval Research Laboratory (NRL), University of Rochester, Cornell University and Eastman Kodak Company is an important step to the use of the nan...
Physics and Astronomy | Read moreNew Nanocrystals Show Potential for Cheap Lasers, New Lighting
The findings, detailed online in today's issue of Nature, may open the door to dramatically less expensive and more versatile lasers, brighter LED lighting, and biological markers that track how ...
Physics and Astronomy | Read moreResearch highlights potential for improved solar cells
A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication—when a photon creates multiple electrons—is a real phenomenon in tiny semiconductor crystals and not a false...
Life Sciences | Read moreQuantum Dots May be Toxic to Cells, Environment Under Certain Conditions
Their study, the first to report on how different pH levels may affect the safety of QDs, appears in the Jan.15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal. In the...
Ecology, The Environment and Conservation | Read moreNew research expected to improve laser devices and make photovoltaics more efficient
"Slowing down the cooling of these electrons—in this case, by more than 30 times—could lead to a better infrared laser source," said Philippe Guyot-Sionnest, Professor of Chemistry and Physi...
Life Sciences | Read moreHybrid Materials For Future Solar Cells
Semiconductor nanocrystals or also called quantum dots exhibit outstanding optical properties compared to organic dyes. Due to the quantum confinement their emission color can be continuously tuned fr...
Physics and Astronomy | Read moreTerahertz Goes Nano
Contrary to textbook wisdom, the unusually long illuminating wavelength of 118 µm did not at all preclude researchers from the Max-Planck-Institute of Biochemistry (MPIB) to resolve details as small a...
Physics and Astronomy | Read moreA New Material Could Act as a Nanofridge for Microchips
The significant reduction achieved in these devices often is accompanied by new discoveries in how they behave precisely when the systems are of extremely small dimensions. Understanding this new phys...
Physics and Astronomy | Read moreMicrowave Synthesis Connects with the (Quantum) Dots
By using a laboratory microwave reactor to promote the synthesis of the widely used nanomaterials, the recently published* NIST process avoids a problematic step in the conventional approach to making...
Materials Sciences | Read moreJILA solves problem of quantum dot 'blinking'
Scientists at JILA have found one possible way to solve the blinking problem and have induced quantum dots to emit photons (the smallest particles of light) faster and more consistently.The ad...
