Good vibrations give electrons excitations

Good vibrations give electrons excitations
Oak Ridge TN (SPX) Nov 11, 2014 - For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely. Some scientists sided with Nobel Prize-winning physicist Nevill Mott in thinking direct interactions between electrons were the key. Others believed, as did physicist Rudolf Peierls, that atomic vibrations and distortions trumped all ... more
