New way to process OLEDs discovered

By / April 6, 2010

A Lawrence Berkeley National Lab research team has discovered a new way to process white OLEDs for solid-state lighting. OLEDs based on organic and/or polymer semiconductor materials can cover large-area displays or panels using low-cost processing techniques. Single-color OLED displays are already available commercially. A mix of red-, green- and blue-emitting materials can be used…

Solid-state photovoltaics offer new path to solar energy

By / March 30, 2010

According to a Lawrence Berkeley National Laboratory press release, researchers have discovered a new path to convert sunlight to electricity. Researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin films. This new route to energy production overcomes the bandgap voltage limitation that continues to be detrimental to…

Nitride with silicon: solar cells with 30% efficiency?

By / September 30, 2009

A Phoenix company said it has created a hybrid solar cell that pairs a gallium-nitride thin film with typical silicon-based PV technology to produce a single unit it claims can achieve an efficiency of 25 percent to 30 percent. RoseStreet Labs Energy announced the prototype cell Monday, and it expects to start commercial production late…

Individual Carbon Atoms in Motion

By / April 9, 2009

This video is no more, or less, than watching for the first time, in real-time, individual carbon atoms being knocked off the edges of a hole in a sheet of graphene while other atoms break and recreate bonds as they shift around in response, looking for the most stable position.

Video of the week – The sight of individual carbon atoms in motion

By / April 1, 2009

[flash /ceramictechtoday/wp-content/video/moving_carbon_atoms.flv mode=1 f={image=/ceramictechtoday/wp-content/video/moving_carbon_atoms.jpg}] This is a brief video. Maybe I am overwhelmed by this because of my chemistry background, but in my opinion, this video documents what truly should be “wow”-level historical type of moment in material-related sciences. As the folks at the Lawrence Berkeley Nation Lab note, this is equivalent to the first…

New ‘domains’ for nano electronics

By / February 9, 2009

Researchers say that logic and memory functions of future electronic devices could shrink an order of magnitude (one or two nanometers, instead of tens of nanometers) if they can control domain walls, the transition zones in a material that separate regions of different magnetic, electric or other properties. And, by “control,” the researchers remarkably mean…

Chu, scientist and Nobel laureate, tapped for DOE head

By / December 11, 2008

There’s a ripple of excitement in the science and technical community. Imagine – an experienced scientist and successful administrator with a breadth of knowledge at the helm of the Department of Energy. Given the role DOE is going to play in the next few years, the selection of Steven Chu comes at a critical time.…
