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.

Carbon nanotube double quantum dot
Dark-field optical microscope image of a carbon nanotube grown over pre-patterned contacts and gate electrodes. With Charles Marcus group, Harvard University.
Carbon nanotube growth
SEM image of CVD-grown carbon nanotubes, contrast inverted. With Charles Marcus group, Harvard University.
Carbon nanotube quantum dot
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.
Curled platinum-gold metal bilayer
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.
InSb superconducting nanowire device
An InSb nanowire is contacted on the left by gold and on the right by the superconductor NbTiN for tunneling measurements. With Charles Marcus group, Harvard University.
