844. Anomalous Peak Current Observed in Scanning Tunneling Microscopy IZ Spectra of Silicon

William Brunt (University of Alberta)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The magnitude of the tunneling current at a fixed bias in scanning tunneling microscopy (STM) is exponentially dependent on the distance between the tip and the sample as observed by recording IZ spectra. Here we report reproducible IZ spectra recorded over Si(100), with and without H-termination. While spectra taken over a dangling bond display an initial rise in current with decreasing...

757. Scanning Tunneling Microscopy study of the surface confined self-assembly of aldehyde functionalized molecules on Au(111)

Dr Hamzeh Nakhaei Niya (Lakehead)

Oral (Non-Student) / Orale (non-étudiant(e))

The formation of one- and two-dimensional (1D & 2D) molecular structures at the nanoscale rely on the self-assembly of organic molecules with interacting functional groups on solid single crystal substrates. Molecules containing aldehyde functional groups are promising candidates for the formation of 2D self-assembled networks and the subsequent formation of robust covalent networks [1,2].
