abstract = {Progress in the emerging fields of atomic and
close-to-atomic scale manufacturing is underpinned by
enhanced precision and optimization of laser-controlled
nanostructuring. Understanding thin films' crystallographic
orientations and microstructure effects becomes crucial for
optimizing the laser-metallic thin film interactions;
however, these effects remain largely unexplored at the
atomic scale. Using a hybrid two-temperature model and
molecular dynamics, we simulated ultrafast laser-metal
interactions for gold thin films with varying
crystallographic orientations and microstructure
configurations. Microstructure features, namely grain size,
grain topology, and local crystallographic orientation,
controlled the rate and extent of lattice disorder evolution
and phase transformation, particularly at lower applied
fluences. Our simulations provided comprehensive insights
encompassing both the nanomechanical and thermodynamic
aspects of ultrafast laser-metal interactions at atomic
resolution. Microstructure-aware/informed thin film
fabrication and targeted defect engineering could improve
the precision of nanoscale laser processing and potentially
emerge as an energy-efficient optimization strategy.},
