Evolution of periodicities along the orthorhombic axes as a function of film thickness: (a) out-of-plane ZnO , (b) in-plane ZnO and (c) in-plane
[0001] directions; (d) a and (e) γ unit-cell parameters; (f) unit-cell volume. Particular uncertainty has been indicated for each point; when error bars are not seen, it is because uncertainty is lower than the size of the symbol. |
