Abstract: We study conserved models of crystal growth in one dimension ( t z ( x , t ) = - x j ( x , t )) which are linearly unstable and develop a mound structure whose typical size L increases in time ( L ~ t n ). If the local slope ( m = x z ) increases indefinitely, n depends on the exponent characterizing the large- m behaviour of the surface current j ( j ~1/| m | ): n = (1/4) for 1 3 and n = (1+ )/(1+5 ) for >3.
