Nature communications 14 1, 3147, 1-7 (2023)

The quest to improve transparent conductors balances two key goals: increasing electrical conductivity and increasing optical transparency. To improve both simultaneously is hindered by the physical limitation that good metals with high electrical conductivity have large carrier densities that push …

Strain and Temperature Dependence of the Electronic Structure of Sr2RuO4 Investigated by ARPES
Andrew Scott Hunter

Thèse (2023)

In its normal state, Sr2RuO4 is a prototypical Fermi liquid below ∼ 25 K. At ∼ 1.5 K it undergoes a superconducting transition, but it has long remained challenging to determine the symmetry or order parameter of the superconducting state. Recent experiments have shown…
