(Color online) (111)A and B OH terminated surface undergoing transformation indicated by reactions (1)(right) and (2)(left). O, As, Ga, and H atoms are represented by red, larger white, grey, and smaller white spheres, respectively. The box indicates the (2X1) unit cell used in our calculations.
(Color online) Interface structures obtained at the end of the first cycle of ALD half-reactions on (111)A and B, respectively. Al atoms are represented by yellow spheres.
(Color online) Plot of DOS versus energy for the structures shown in Fig. 2 compared with the DOS of bulk GaAs.
