"Growth Mechanisms and Growth Kinetics for Oxide-Oxide Vertically Aligned Nanocomposite Thin Films"

By
Di Zhang
Purdue MSE Ph.D. Preliminary Exam

Advisor: Professor Haiyan Wang

ABSTRACT

In this review article, the strain states and growth mechanisms of oxide-oxide vertically aligned
nanocomposite (VAN) thin films are discussed. The VAN films have highly tunable strain states
including in-plane and out-of-plane strains. By strain tuning good epitaxy of large lattice
mismatched materials and variable physical properties could be achieved. Two basic growth
mechanisms-(a) nucleation and growth and (b) (pseudo-) spinodal decomposition-and growth
kinetics are reviewed respectively with typical examples. After pointing out some discrepancies incurrent growth theories and unresolved questions in VAN research field, several promising
techniques and future outlooks of this field are outlined.
Key words: strain, growth mechanism, vertically aligned nanocomposite
