Thin Imager Opens Large-scale Window into the Infrared
SAN DIEGO, May 7, 2021 — A study introduced by a group led by electrical engineers at the University of California, San Diego describes a thin, large-scale device that converts infrared light into images. Tests showed that the imager can be used to see through smog and...
More Efficient Solar Cells with a One-Step Process
HOUSTON, June 20, 2014 — A new one-step process for producing efficient materials could mean big things for solar cells. Developed by a team at Rice University, the new process produces black silicon. This material reflects almost no light. Its textured surface of nanoscale...
Storex Tech Study Clears Optical Lithography Hurdle
WILMINGTON, Del., and BUCHAREST, Romania, Feb. 13, 2014 — Storex Technologies Inc. has developed an optical lithography technique with a resolution of 1 nm half-pitch lines, clearing a major hurdle in this field. Many attempts have been made to break the diffraction limit, which Storex researchers said has...
Phase-Shifted Flat Lens Creates Perfect Image
CAMBRIDGE, Mass., Aug. 24, 2012 — By moving the phase shifting of light to the surface of a lens instead of creating phase delays as it propagates through a material, Harvard engineers have created an ultrathin, flat lens that could potentially replace bulk components in optical...
Dopant Breaks Graphene Solar Efficiency Record
GAINESVILLE, Fla., May 25, 2012 — Chemically treated graphene has upped the material’s solar power conversion efficiency from 2.9 percent to a record-breaking 8.6 percent. Researchers at the University of Florida have taken graphene, a single-atom-thick lattice of carbon...
Spectrometer-on-a-chip shows young universe
GREENBELT, Md. – NASA scientists hoping to get a glimpse of the universe in its youth may finally do so using a revolutionary instrument on a chip called MicroSpec. Scientists know what the universe looked like when it was a baby and how it looks today, but...
First light-absorbing anti-laser built
NEW HAVEN, Conn. – More than 50 years after the invention of the laser, scientists have built the world’s first anti-laser, paving the way for novel technologies with applications in everything from optical computing to radiology. Scientists at Yale...
Growing inexpensive silicon microwires
CAMBRIDGE, Mass. – A new, simpler process has been developed that turns silicon into precisely sized and spaced microwires with the potential for practical commercial applications such as solar cells, transistors, integrated circuits, sensors and batteries. ...
‘Pin Art’ Mass Produces Nanowires
GAITHERSBURG, Md., Aug. 9, 2010 — Researchers at the National Institute of Standards and Technology (NIST) have cultivated many thousands of nanocrystals onto silicon, a step they say will bring us closer to reliable mass production of semiconductor nanowires. Dubbed...
Bending Light at will with Transformation Optics
May 10, 2010 — Invisibility cloaks get all the publicity, but they may just be the beginning if the promise of transformation optics can be realized. The discipline could lead to smaller photonic and electronic devices and more cost-competitive solar cells –...
Nanogenerators Power New Sensors
ATLANTA, Ga., March 29, 2010 — By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of...
PW2010: New at Newport
SAN FRANCISCO, Jan. 28, 2010 – Newport Corp. has come to SPIE Photonics West this year not only with new products but with a whole new brand strategy. Kim Abair, director of global marketing at the Irvine, Calif.-based Newport Corp., discussed the company’s newly launched...
Mess-Free Graphene Growth
ITHACA, N.Y., Nov. 16, 2009 – A research team at Cornell University invented a simple, less expensive way to make graphene electrical devices by growing graphene -- one-atom-thick layers of carbon -- directly onto a silicon wafer.
3-D Nanofluidic Devices
GAITHERSBURG, Md., April 1, 2009 – By manufacturing integrated circuits at the nanometer level, a method was devised for creating nanofluidic devices with complex 3-D surfaces.
Surface Repels Most Liquids
MADISON, Wisc., Feb. 5, 2008 -- The surface of a new material repels virtually all liquids, then absorbs them when a jolt of electricity is applied. Made of tightly packed nanostructures resembling tiny nails, the material could be used in biomedical applications such as...
Silicon Spin Chip Made
NEWARK, Del., Oct. 30, 2007 -- The first researchers to demonstrate that an electron's spin can be electrically injected, controlled and detected in silicon have now shown that these "hot" electrons can be transported through an entire silicon wafer, paving the way for the...
Two Colors, One Dopant
Jul 1, 2007 — A group of researchers from the Institute of Ion Beam Physics and Materials Research at Forschungszentrum Dresden-Rossendorf in Germany has discovered that the rare-earth element europium can do something rare. When used in a silicon wafer as a...
Obstacle to Mass-Producing Microchips Removed
PRINCETON, N.J., Jan. 18, 2007 -- By eliminating tiny air bubbles that form when liquid droplets are molded into intricate circuits, researchers said they are dissolving a sizable obstacle to mass-producing smaller, cheaper microchips. A team at Princeton University led by...
Isonics' Semiconductor Division Hires Quality Director
Jan 11, 2007 — Isonics Corp. of Golden, Colo., announced today that Patrick Taylor has joined its semiconductor division as director of quality assurance. The company said it hired Taylor to support the significant growth that the division, based in Vancouver,...
Hamamatsu Corporation Wins Circle of Excellence Award
Jan 1, 2004 — Manufactured from a single 12-in. silicon wafer using conventional CMOS processes, the C7930DP flat panel sensor was developed by Hamamatsu Corp. of Bridgewater, N.J., for low-energy mammography, biopsy and traditional nondestructive test...
New Semiconductor Lithography Makes a Splash
Oct 1, 2003 — Semiconductor manufacturers are about to be all wet. But that's a good thing. A new technique called immersion lithography could allow the industry to continue tracking Moore's law, which forecasts substantial annual decreases in state-of-the-art...
Photonic Crystal Improves Mid-IR Generation
Feb 1, 2003 — A photonic crystal designed into a silicon wafer promises users the ability to controllably generate radiation at mid-infrared wavelengths. The emitter, developed by Ion Optics Inc. in Waltham, Mass., in conjunction with researchers at the Jet...
