Resumen:
A finite temperature version of body-centered
solid-on-solid growth models involving attachment and
detachment of dimers is discussed in 1+1 dimensions. The
dynamic exponent of the growing interface is studied
numerically via the spectrum gap of the underlying
evolution operator. The finite size scaling of the latter
is found to be affected by a standard surface tension
term on which the growth rates depend. This non-universal
aspect is also corroborated by the growth behavior
observed in large scale simulations. By contrast, the
roughening exponent remains robust over wide temperature
ranges.
