February 2024- Our new paper showing how thin films can be used as model systems to understand deep-Earth phase transformations was published in Springer-Nature's Communications Earth & Environment. Click here for the publication |
 |
January 2024- Our new Pulsed Laser Deposition (PLD) system was installed! With conventional Pt-heater substrate temperatures up to 1000C, and even higher tempertures available with the optional laser heater, this system promises to allow us to produce a range of novel thin films with tailored grain size, film stress, grain orientation, and composition.
