A team of University of British Columbia researchers has developed a
technique that controls the number of electrons on the surface of
high-temperature superconductors, a procedure considered impossible for
the past two decades.

Led by Physics Assoc. Prof. Andrea
Damascelli, the team deposited potassium atoms onto the surface of a
piece of superconducting copper oxide. The approach allows the
scientists to continuously manipulate the number of electrons on
ultra-thin layers of material.

The details are published this week in the prestigious journal Nature Physics.

Superconductivity
– the phenomenon of conducting electricity with no resistance – occurs
in some materials at very low temperatures. High-temperature
superconductors are a class of materials capable of conducting
electricity with little or no resistance in temperatures as high as
-140 degrees Celsius.

"The development of future electronics,
such as quantum computer chips, hinges on extremely thin layers of
material," says Damascelli, Canada Research Chair in the Electronic
Structure of Solids.

"Extremely thin layers and surfaces of
superconducting materials take on very different properties from the
rest of the material. Electrons have been observed to re-arrange,
making it impossible for scientists to study," says Damascelli. "It’s
become clear in recent years that this phenomenon is both the challenge
and key to making great strides in superconductor research.

"The
new technique opens the door to systematic studies not just of
high-temperature superconductors, but many other materials where
surfaces and interfaces control the physical properties," says
Damascelli. "The control of surfaces and interfaces plays a vital role
in the development of applications such as fuel cells and lossless
power lines, and may lead to new materials altogether."

The
superconductors Damascelli’s team experimented on are the purest
samples currently available and were produced at UBC by physicists Doug
Bonn, Ruixing Liang and Walter Hardy.

Part of the study was
carried out at the Advanced Light Source synchrotron in California. In
the future, the design and study of novel complex materials for
next-generation technologies will be carried out at the Quantum
Materials Spectroscopy Center currently under construction at the
Canadian Light Source in Saskatoon under Damascelli’s leadership.

Here is the video of Brian Greene on string theory. This is part of my insight into the LHC, the who’s what and whys. Although Brian Greene is not working on the LHC himself I still feel this is relevant and can explain some underlying annoyances I didn’t quite get and goes nicely with the first video from Brian Cox, Brian Cox on CERN’s supercollider.

I recently got back into watching the talks on Ted.com. Reason for this being is that I picked up on a video about the CERN Supercollider. I found this Brian Cox’s talk to be a great help in my understanding of what the CERN project is all about, the shear size of the project and the reasons behind this idea. Enjoy
