Element-Specific Orbital Character in a Nearly-Free-Electron Superconductor AgPbO Revealed by Core-Level Photoemission
Soobin Sinn, Kyung Dong Lee, Choong Jae Won +8
AgPbO has attracted considerable attention due to its novel nearly-free-electron superconductivity, but its electronic structure and orbital character of the Cooper-pai…
Contact holes in vertical electrode structures analyzed by voltage contrast-SEM and conducting AFM
Minsun Gu, Moon Seop Hyun, Moonsup Han +2
Soaring demands of multi-stacked memory devices request urgent development of backside contact electrode technologies, such as high aspect ratio etching, metallization, and inspect…
Observation of Kondo hybridization with an orbital-selective Mott phase in 4d Ca2-xSrxRuO4
Minsoo Kim, Junyoung Kwon, Choong H. Kim +12
The heavy fermion state with Kondo-hybridization (KH), usually manifested in f-electron systems with lanthanide or actinide elements, was recently discovered in several 3d transiti…
Electronic and magnetic properties of single-layer MPX metal phosphorous trichalcogenides
