Absence of Metallicity in K-doped Picene: Importance of Electronic Correlations
Absence of Metallicity in K-doped Picene: Importance of Electronic Correlations
Potassium-doped picene (K(x)picene) has recently been reported to be a superconductor at x=3 with critical temperatures up to 18 K. Here we study the electronic structure of K-doped picene films by photoelectron spectroscopy and ab initio density functional theory combined with dynamical mean-field theory (DFT+DMFT). Experimentally we observe that, except …
