Formation, structure and electronic structure of ultrathin Ag films on V(100): experiments and calculations

One of the intriguing electronic phenomena in ultrathin films is the formation of so-called quantum well state s (QWS). Our research is focused to ultrathin silver films on V(100) in the limit of small thicknesses (1-5 layers). Due to the profound difference of the band structure of two metals, sp and d QWS are formed, dominating large parts of valence band region. We study the formation, structure and electronic structure of the system. Experiments were performed in three different ultrahigh vacuum systems: in Zagreb (STM, LEED, ARPES, AES), Bonn (STM, AES) and in Trieste at Elettra synchrotron (ARPES, LEED). The ab initio calculations were perfonned in the DFT approach, using DACAPO code.
