Electrode surface topology enhanced KTN deflector
Abstract
In this letter we present the first study on the electrode surface topology enhanced KTN deflector, in which one of the electrodes contains sharp edges. In this case, the electric field can be enhanced near the sharp edge. This can increase the injected charges, which in turn results in the increased deflection angle for the space charge controlled KTN deflector. Both the conducted simulations and experimental investigations agreed well. In the experiments, the sharp edge structures were created by two methods: nanofabrication and roughing with a sandpaper. Both cases experimentally obtained increased deflection ranges. This study would be beneficial to many deflector applications because it can enlarge the deflection angle without the need to increase the driving voltage.
