Tuneable electron-phonon scattering graphene

There is a nice article by Michael S. Fuhrer in Physics about tuning the Fermi surface area in graphene and using it to observe qualitatively different temperature dependence of the resistivity due to electron-phonon scattering.

The legacy of 40 years of cuprate superconductivity

In February 1986, Bednorz and Müller made a stunning discovery: superconductivity at a temperature of 35 K in a doped copper oxide (cuprate)...
