As recounted by Dan Agin in his book Junk Science, soon after Schön published his work on single-molecule semiconductors, others in the physics community alleged that his data contained anomalies. Julia Hsu and Lynn Loo originally noticed issues with Schön's paper describing the assembly of molecular transistors whilst attempting to patent research on lithography, realising by accident that Schön had duplicated figures.[5] Hsu and Loo had attempted initial experiments to gather evidence for their patent but relied on the scientific outcomes of Schön's work.
