What controls the superconducting dome of electron-doped FeSe?

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | Summary:Superconducting domes are conspicuous features of the phase diagrams of most unconventional and high-temperature superconductors. The superconducting transition temperature ($T_c$) of FeSe can be dramatically enhanced with electron doping, but unlike all other high-temperature and unconventional superconductors, its full phase diagram and superconducting dome have yet to be fully explored. […]

Defect-engineered scaling of lead-free ferroelectrics with ultralow-voltage switching

Posted by klaurent Cornell

Kavli Affiliate: David Muller | Summary:Scaling ferroelectrics to nanometer thicknesses remains a central challenge for low-power, nonvolatile electronics, as leakage currents increasingly dominate with reduced dimensions. Alkali-based, lead-free ferroelectrics offer an environmentally sustainable alternative to lead-based systems, yet their scaling is severely limited by leakage arising from volatile alkali constituents. Here, we show that this […]
