Work and studies of metal films and thin films as well as their fabrication has been going on for more than a century. Basically since electromagnetism is popular. Fabrication tools for thin films have improved a lot over the past decades though. We can now fabricate exotic structured matter at the nanoscale that doesn't respond as the bulk counterpart.
