Simple process for ‘two-faced’ nanomaterials may aid energy,
information tech

A team led by the Department of Energy’s Oak Ridge
National Laboratory used a simple process to implant atoms
precisely into the top layers of ultra-thin crystals, yielding
two-sided structures with different chemical compositions. The
resulting materials, known as Janus structures after the two-faced
Roman god, may prove useful in developing energy and information
technologies.
