Kyle Shen and the “Infinite Layer”

Materials scientists at Cornell have taken another step closer to high-temperature superconductors.  Working with strontium-lanthanum cuprates, professor or physics Kyle Shen and collaborators created a superconductor at 100 Kelvin (-280 F, which is pretty warm for these researchers).  The work was published in the December 27 Physical Review Letters.

The group was observing the properties of strontium-lanthanum cuprates, nicknamed the “infinite layer” when doped with extra electrons.  When cooled the electrons undergo a phase transition and become superconducting, which means electrons can flow freely through them without resistance.

Scientists have previously studied strontium-lanthanum cuprates that are hole-doped – meaning electrons are removed from the material.  It was assumed that the materials should respond in the same way to hole doping and electron doping.  Shen’s results now show this needs to be studied further.

Kyle Shen’s work on Cover of Nature Materials

Prof of Physics Kyle Shen with a team of Cornell researchers including PhD candidates Eric Monkman, Daniel Shai, John Harter, and Bulat Burganov have recently published a paper showing how many-body interactions can be engineered at correlated oxide interfaces, an important prerequisite to exploiting such effects in novel electronics.  Their work is on the cover of the October edition of Nature Materials.

Prof. Shen joined Cornell in 2007 and has since been named a National Academy of Sciences Kavli Frontiers Fellow, and

has received the Air Force Office of Scientific Research Young Investigator Award, Presidential Early Career Award for Scientists and Engineers (PECASE), and the Office of Naval Research Young Investigator Award.
