NWO support takes pulsed laser deposition to next level

The Dutch Research Council (NWO) has awarded 4.7 million euros to a consortium led by Differ for setting up a pulsed laser deposition (PLD) lab aimed at energy materials research. The facility will allow science and industry to create relatively large patches of tailor-made thin films and perform in-situ analysis using a range of available diagnostic tools. Applications include solar panels, catalysts for hydrogen production and batteries.

In PLD, a material is shot with a laser pulse, creating a ‘plume’ of plasma that subsequently deposits on a substrate as an extremely thin film. By shooting different targets in a predetermined sequence, materials made-to-order can be created layer by layer. Such nanomaterials may feature unique characteristics that can’t be obtained by other means.

Although PLD is an established technique in academia, limitations with respect to sample size have hindered its application in industry. The PLD4Energy lab intends to bridge that gap by providing the ability to create thin-film samples with a diameter of up to ten centimeters. “There’s no equivalent facility in the world. It lends itself to fundamental research and the next, essential step – the actual implementation,” says Differ’s Anja Bieberle, who leads the consortium.
