We . have developed a novel approach to deposit oxide . . nanostructured thin films via a simple solution chemistry. This approach uses a continuous-flow microreactor to continuously generate a flux of nanoparticles which then impinge on a heated substrate surface. The thin film formation follows a simple particle sticking mechanism. For example, highly transparent nanocrystalline ZnO thin films and exhibit a larger optical bandgap at 4.35 eV were deposited using this technique. Functional ZnO MISFETs were successfully fabricated using this technique after a post air annealing process. In addition to ZnO, we have also deposited, Fe.
