Survival of the metallic state in a single-hole multiband -orbital molecular system
Keisuke Matsui, Ryan A. Klein, Naoya Yoshikane +14
Strong correlations and ferromagnetic Hund's coupling lead to diverse electronic phenomena in transition-metal oxides that sensitively depend on the -orbital electron filling. F…

Robust Metal-Insulator Transition Despite Surface Dead-Layer Growth in Sub-10-nm Cr-Doped V2O3 Nanocrystals
Yoichi Ishiwata, Ichidai Harada, Masaki Imamura +9
We investigated the size dependence of the metal-insulator transition (MIT) in Cr-doped V2O3 nanocrystals by photoemission spectroscopy using complementary probing depths, together…

Narrowing band gap chemically and physically: Conductive dense hydrocarbon
Takeshi Nakagawa, Caoshun Zhang, Kejun Bu +14
Band gap energy of an organic molecule can be reduced by intermolecular interaction enhancement, and thus, certain polycyclic aromatic hydrocarbons (PAHs), which are insulators wit…
