For instan e, annealed below 400 e , the film is amorphous; however, at annealing temperatures of 400 e or 600 e , anatase and rutile omes into being, respe tively. At an annealing temperature higher than 1000 e , anatase phase turns into rutile phase ompletely.As annealing temperature rises up from 400 e to 1000 e , the grain size grows and the surfa e rough- ens, but turning around at 1000 e abruptly, possibly be ause of the phase transition.
