Fig. 7. Photographs of the Cu WE electrodeposited from the G2 bath at —2 V vs. Al QRE: (a) obverse side and (b) reverse side, which appeared by peeling off the deposits with an adhesive tape. The XRD measurements shown in Fig. 8 confirmed that the deposits consisted of crystalline Al metal without trace impurities such as Al,03; in the case of potentiostatic electrodeposition at —1V vs. Al QRE [47] the XRD profiles also show the deposits were
