"For seminal achievements in solar cells and strained quantum well lasers, and especially for creating the field of photonic crystals, spanning both fundamental science and practical applications of that science."
Background:
Eli Yablonovitch received his B.Sc. in physics from McGill University in 1967 and his Ph.D. in Applied Physics from Harvard University in 1972. He is currently Director of the NSF Center for Energy Efficient Electronics Science (E3S), a multi-University Center headquartered at Berkeley. In...
To the surprise of chemists, a new technique for taking snapshots of molecules with atomic precision is turning up chemicals they shouldn’t be able to see.
Chemical reactions take place so rapidly – often within picoseconds, or a trillionth of a second – that chemists expect intermediate steps in the reaction to be too brief to observe. Only lasers firing in femtosecond bursts – like a strobe flashing every thousandth of a picosecond – can capture the fleeting molecular structures that reacting chemicals form on their way to a final product.
Carol T. Christ, interim executive vice chancellor and provost at UC Berkeley, sent this message today to the campus community:
Dear Colleagues:
I am pleased to announce the appointment of Professor Tsu-Jae King Liu as vice provost for academic and space planning, for an initial two-year period with the possibility of extension at the discretion of the next chancellor and my successor.
Tsu-Jae joined the Berkeley faculty in 1996, as assistant professor in the Department of Electrical Engineering and Computer Sciences (EECS), becoming full professor in 2003....
For the lastest BLPA seminar : Series X, We were pleased to host Paul Alivisatos, Vice-Chancellor for research at University of California, Berkeley, and former director of Lawrence Berkeley National Laboratory !
Bringing opposing forces together in one place is as challenging as you would imagine it to be, but researchers in the field of optical science have done just that.
Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have for the first time created a single device that acts as both a laser and an anti-laser, and they demonstrated these two opposite functions at a frequency within the telecommunications band.
Their findings, reported in a paper published today in the journal Nature Photonics, lay the groundwork for...
Light-emitting, four-armed nanocrystals could someday form the basis of an early warning system in structural materials by revealing microscopic cracks that portend failure, thanks to recent research by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley.
The researchers embedded tetrapod-shaped quantum dots, which are nanosized semiconducting particles, in a polymer film. The tetrapods’ cores emit fluorescent light when their arms are twisted or bent out of shape. This indicates the polymer is undergoing a degree of...
Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have created a sort of nanoscale display case that enables new atomic-scale views of hard-to-study chemical and biological samples.
Their work, published online Aug. 18 in the journal Science, could help to reveal new structural details for a range of challenging molecules—including complex chemical compounds and potentially new drugs—by stabilizing them inside sturdy structures...
In an advance that helps pave the way for next-generation electronics and computing technologies—and possibly paper-thin gadgets —scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) developed a way to chemically assemble transistors and circuits that are only a few atoms thick.
What’s more, their method yields functional structures at a scale large enough to begin thinking about real-world applications and commercial scalability.
Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material.
Solar cells made from compounds that have the crystal structure of the mineral perovskite have captured scientists’ imaginations. They’re inexpensive and easy to fabricate, like organic solar cells. Even more intriguing, the efficiency at which perovskite solar cells convert photons to electricity has increased more...
Jarrod McClean and his Lawrence Berkeley National Laboratory colleagues want to simulate and predict the chemistry and properties of advanced compounds before scientists go into the lab to make them.
But they have a problem. Today’s high-performance computing (HPC) systems aren’t powerful enough to model materials with the detail and accuracy the researchers need: at the level of electron arrangements and interactions in molecules. Today’s classical computers with memory comprised of bits could take years to perform such calculations, even with the most powerful machines available...
