deposited. For example, in Fig. 4.20 the deposition nanostructured ZnO by<br />

RF magnetron sputtering onto different substrates is shown, where the<br />

morphology and crystal structure are markedly different on various substrate<br />

surfaces.<br />

on aluminum (left) and bare LiNbO3 (right).<br />

There are also several modifications that can be made to traditional<br />

sputters. Sputters with such modifications include ion-beam sputtering
