  A theoretical model which takes into account the structural distortion of
double-crossover DNA tiles has been studied to investigate its effect on
lattice formation sizes. It has been found that a single vector appropriately
describes the curvature of the tiles, of which a higher magnitude hinders
lattice growth. In conjunction with these calculations, normal mode analysis
reveals that tiles with relative higher frequencies have an analogous effect.
All the theoretical results are shown to be in good agreement with experimental
data.
