Popis:	We have investigated the interface formation of Ca with an alkanethiol CH3(CH3)17SH monolayer self‐assembled onto gold‐coated silicon. Deposited Ca neither diffused into nor interacted chemically with the monolayer. Core‐level shift and work function changes were observed in the monolayer as soon as Ca was deposited and they were stabilized after 8 A of Ca coverage. The shifts are interpreted in terms of charge transfer from Ca to the monolayer, creating a dipole layer at the interface.
