abstract = {SrRuO3 thin-films were deposited with different pulse
repetition rates, fdep, epitaxially on vicinal SrTiO3
substrates by means of pulsed laser deposition. The
measurement of several physical properties (e.g.,
composition by means of X-ray photoelectron spectroscopy,
the out-of-plane lattice parameter, the electric
conductivity, and the Curie temperature) consistently
reveals that an increase in laser repetition rate results in
an increase in ruthenium deficiency in the films. By the
same token, it is shown that when using low repetition
rates, approaching a nearly stoichiometric cation ratio in
SrRuO3 becomes feasible. Based on these results, we propose
a mechanism to explain the widely observed Ru deficiency of
SrRuO3 thin-films. Our findings demand these theoretical
considerations to be based on kinetic rather than widely
employed thermodynamic arguments.},
