Straight and bent SnO_2 whiskers were grown by oxidizing Sn. Straight whiskers obtained are classified into four types growing in the [011], [100], [111] and [110] directions. Bent whiskers are composed of some coherent element whiskers among three types of straight whiskers growing in the [011], [100] and [111] directions. They usually have a common (011) surface on which isosceles triangular mounds and many steps are seen. The growth direction of the whiskers is easily identified from the orientation of the triangular mound and of the step found on the (011) plane.
