Semiconductivity and photoconductivity have, among other properties of nanowires, potential applications in the next generation of electronic and photonic devices such as transistors, solar cells, LEDs and detectors. In order to be able one day to utilize these unique properties, further characterization of single nanowires is still needed.
This application note reports on the use of Imina Technologies miBot manipulators to carry out the delicate step that consists in positioning the nanowires grown by metalorganic chemical vapour deposition (MOCVD) at specific locations on the substrate.
The above video illustrates this challenging handling operation, showing two miBot nanomanipulators used to extract nanowires from a large bundle and contact them with sharp tungsten probes. Motions are in real-time, demonstrating the rapidity and precision of the procedure as well as the vibration free displacements even at high optical magnifications. This is further exemplified with the transfer of nanowires from one probe to another.
