Single Stage Homogenous Deposition of Isolated Nano particles

We demonstrate that a controlled and homogenous distribution of isolated nano-particles can be achieved in deposition by employing a single stage deposition technique, utilizing a commercial ultrasonic humidifier to produce micrometer scale droplets from a suspension containing nano particles. Nano-diamonds were uniformly distributed on a Si substrate using this method. P article density was controlled by varying the deposition time. The spatial distribution of the nano particles is shown to be uniform and with no aggregation. We propose that this method can be utilized in developing mass production processes of nano devices where a homogenous sub monolayer of nano-particles is required.
