Bandwidth-control orbital-selective delocalization of 4f electrons in epitaxial Ce films

The mechanism of the delocalization transition of 4f electrons in closely-packed Ce metal has been debated. Here, the authors present photoemission evidence for bandwidth-controlled Mott delocalization in a previously unreported structural phase of thin epitaxial Ce films obtained by thermal anneali...
