A century ago, Walter Rosenhain proposed that metals have amorphous layers at their grain boundaries. This has since been shown experimentally to be false, but now the idea has been revived for a different material. A computer simulation has shown that between silicon crystal grains with a certain range of orientations, there should be a stable glassy layer.
