At just a molecule thick, it’s a new record: The world’s
thinnest sheet of glass, a serendipitous discovery by scientists at Cornell and
Germany’s University of Ulm, is recorded for posterity in the Guinness Book of
World Records.
The “pane” of glass, so impossibly thin that its individual
silicon and oxygen atoms are clearly visible via electron microscopy, was
identified in the lab of David A. Muller, professor of applied and engineering
physics and director of the Kavli Institute at Cornell for Nanoscale Science.
