Pulsed Laser Deposition Lab

The IMW runs Physical Vapor Deposition (PVD) laboratories with two larger Pulsed Laser Deposition (PLD) clusters, a stand-alone PLD setup as well as two sputter deposition systems. The setup includes several UHV chambers with load lock systems for the preparation of epitaxial and polycrystalline magnetic, shape memory and superconducting thin films as well as for oxide heterostructures. Besides state-of-the-art RHEED systems for in-situ control of film growth, specialized systems are available for ion-beam assisted and off-axis PLD.
