Strain-free epitaxy of germanium film on mica

more »
Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it's making a comeback. It's generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals' forces to grow germanium on mica.
