Over the years, our Nanoscale Physics Group has
imaged a wide variety of nanoscale objects. Below we list in no
particular order some of the more interesting ones.
The Intel logo made using our early
lithographic capabilities to create quantum dots with an SPM.
The logo size is roughly comparable to the
wavelength of green light. Created by M. Paniccia in the
A scanning probe image of a multi-wall
carbon nanotube with three electrical contacts. Elton
Graugnard made the shadow mask and performed the
An SPM image of a Y-junction carbon nanotube. The nanotube was grown in
Rao's group at Clemson University. Image by J. Gaillard.
A dark field image of a Y-junction nanotube
during a nanomanipulation experiment. The photograph was taken
by Jay Gaillard.
Making electrical contact to the arms of a
Y-junction nanotube. The masking was done by Jay Gaillard
using Y-junction nanotubes grown in Prof. Rao's lab at
Clemson. Scott Crtittenden made the scanning probe image.
Step edges on Au(111). Image by A. Labonte.
A transmission electron microscope image of
an ordered array of single crystal Au nanoclusters. The
nanoclusters were grown in the cluster lab of R.P. Andres.
A scanning probe image of a Au
nanocluster, evidently taken just before sunset.
An STM image of a periodic array of
carbon atoms on HOPG. Image by T. Lee.
An SPM image of Sapphire
A UHV STM image of Au triangular islands formed
when gold atoms are evaporated onto a MoS2
substrate. Image by S. Hong.
An STM image of a MoS2
substrate showing atomic resolution. The image was taken under
ultra-high vacuum conditions. Image by S. Hong.
Scanning force microscope image of an
alumina template etched to produce periodic pores. The sample
was prepared by Terry Xu at Northwestern. Image by S. Brown.
A three dimensional rendering of an STM
image of a periodic array of carbon atoms on HOPG.
A scanning probe microscope image of near
monolayer coverage of purple membrane deposited onto a mica
substrate. The image provides clear evidence for the formation
of multiple layers. The image spans an area of 5 microns x 5
microns. Image by S. Crittenden.
An SPM image of contact
line deposits that can form when purple membrane (PM) is deposited
onto a mica substrate. The parallel deposits form
spontaneously during the evaporation of water solvent. The
monolayer ordering of the individual PM patches is clearly
evident. The image spans an area of 16 microns x
16 microns. Image by S. Crittenden.
An STM image of a self-assembled Au cluster
array. The hexagonal lines illustrate the unit cell properties
of the cluster array. A defect vacancy is clearly evident. The
image was taken under ultra-high vacuum conditions.
