When electron beam lithography is done on insulating substrates not coated with a conducting film, exposure of the resist during dielectric breakdown can result in a beautiful failure! Image courtesy of William Shattuck and Peter Gea.

Thin film interference produces all the colors of the rainbow for this extremely cleavable layered antiferromagnet.

Dark-field optical microscope image of a carbon nanotube grown over pre-patterned contacts and gate electrodes.  With Charles Marcus group, Harvard University.

SEM image of CVD-grown carbon nanotubes, contrast inverted.  With Charles Marcus group, Harvard University.

SEM image of a carbon nanotube draped over pre-patterned contact metal.  The metal is lighter where contacted by the nanotube because those lines are shorted together and have a longer RC charging time in the SEM.  With Charles Marcus group, Harvard University.

Bond pads for a device curled up during carbon nanotube growth at 900 degrees C, resulting in this attractive fabrication mistake.  With Charles Marcus group, Harvard University.
