Gold nanoparticle mediated formation of aligned nanotube composite films

Article Abstract:

The formation of highly anisotropic nanotube composite materials made by the attachment of gold nanoparticles to the surface of the single-walled carbon nanotubes followed by the preparation of an aligned composite film by compression in a Langmuir-Blodgett trough is reported. It is stated that these aligned films have highly anisotropic electrical properties with a factor of 3000 differences in the conductivity between the aligned and perpendicular directions.

Platinum nanofilm formation by EC-ALE via redox replacement of UPD copper: Studies using insitu scanning tunneling microscopy

Article Abstract:

The growth of Pt nanofilms on well-defined Au(111) electrode surfaces, using electrochemical atomic layer epitaxy (EC-ALE) and scanning tunneling microscopy (STM) is described. The first atomic layer of Pt deposited resulted in a surface alloy, while deposition of a second Pt atomic layer resulted in formation of a well ordered Pt adlayer, producing a Moire pattern in the atom I layer as well as five atom clusters was seen.

Electronic properties of doped molecular thin films measured by Kelvin probe force microscopy

Article Abstract:

Kelvin probe force microscopy is used to measure the high-resolution electronic properties of doped organic thin-film transistors. The moderate change in doping process is explained by two counter-acting effects on the Fermi energy position, the doping-induced additional charge and the broadening of the density of states.
