Image Gallery

Scanning Probe Microscopes produce images by holding a metal tip within angstroms of a surface, allowing electrons to quantum mechanically tunnel between the tip and a conductive surface. These images show quantum mechanics in action. However, very few scanned probe images actually get published and even fewer become available to the general public. This gallery is intended to show off some of those "other" images. You are highly encouraged to upload images. Make sure to include a title, description, and to whom credit should be given. Please keep the images to somewhere between 128x128 pixels and 1024x1024 pixels.

Au(111) Herringbone

Au(111) Herringbone
Herringbone reconstruction on Au(111). There is an alternating pattern of HCP and FCC regions on this surface, resulting in a beautiful herringbone pattern. Small dark spots are various adsorbates. Aaron J. Bradley Crommie Group 2012

Au(111) Herringbone Reconstruction

Au(111) Herringbone Reconstruction
On the Au(111) surface, there are regions of both HCP and FCC, with a buckled stripe in between. In this image, there is also an interesting grain boundary-like structure. Aaron J. Bradley Crommie Group 2012

Standing Waves on Pt(111)

Standing Waves on Pt(111)
A dI/dV map showing electron standing waves on Pt(111). The dots are various types of adsorbates and the lines are atomic step edges. Aaron J. Bradley Crommie Group 2012

Graphene Defects on Pt(111)

Graphene Defect Ring on Pt(111)

Graphene Pt(111) defect ring
Rings of defects and grain boundary loops often manifest themselves as flower-like structures in graphene grown on metal substrates. This graphene sample was grown through a CVD process on Pt(111). Aaron J. Bradley Crommie Group 2012

Graphene Moire on Pt(111)

Graphene Moire on Pt(111)
Graphene grown through chemical vapor deposition (CVD) on Pt(111). The smaller hexagons belong to the atomic lattice, while the larger superstructure is called a Moire pattern, and is due to a mismatch between the graphene lattice and that of the underlying Pt substrate. Aaron J. Bradley Crommie Group 2012

Graphene Edge on Pt(111)

Graphene on Pt(111)
A small patch of graphene grown on Pt(111) showing a well-defined edge structure. Note the buckling due to lattice mismatch between the graphene and the underlying Pt(111) substrate. Aaron J. Bradley Crommie Group 2012

Ethylene on GaP(110)

Two ethylene (C2H4) molecules adsorbed onto a GaP(110) surface. GaP is a III-V semiconductor with a 2.26eV wide bandgap which is potentially useful for photocatalytic applications. Aaron J. Bradley Miguel M. Ugeda Crommie Group 2012
