The authors study the origin of commensurability oscillation in an antidot lattice in detail, by calcg. magnetoresistance through square, rectangular, and disordered antidot lattices. The authors' calcns. show that the commensurability oscillation in Rxx is mainly detd. by the arrangement of antidots in the Y direction, and vice versa. In the case of a rectangular antidot lattice with b
