Animation of Pulsed Laser Deposition for the Group of Sensor Technologies

This video was made by Captain Corrosion OÜ for the Group of Sensor Technologies (Institute of Physics, University of Tartu) to show the working principle of pulsed laser deposition (PLD), where a pulsing laser beam extracts matter from the target. This extracted matter is then deposited to the substrate. By tuning the level of vacuum in the deposition chamber and the intensity of the laser it is possible to use PLD technology to introduce different modifications into graphene. The Group of Sensor Technologies uses this method to create novel graphene-based gas sensors that can be used for instance for measuring the level of pollution in air.
