Thin Film Formation Through the Array of Colloidal Meso Beads

A convective two-dimensional self-assembly array was used to fabricate dense hexagonal colloidal monolayer on a glass substrate. The dense monolayer sintered at various time and temperature conditions. When the temperature was 160°C, the fully sintered film was achieved within 10 minutes. The resulting film thickness was about 260 nm. The sintering mechanism was explained following Frenkel's viscous model.
