Abstract
The hysteresis of the contact angle of a sessile drop on top of a disordered substrate is studied within a two-dimensional solid-on-solid model using Monte Carlo dynamics. Numerical and analytical evidence is given to show that there is always a hysteresis even for small densities of impurities.
