Simultaneous nanoindentation and electron tunneling through alkanethiol self-assembled monolayers

Article Abstract:

Electrical tunnel junctions consisting of alkanethiol molecules self-assembled on Au-coated Si substrates and contacted with Au-coated atomic force microscopy tips are characterized under varying junction loads in a conducting-probe atomic force microscopy (CP-AFM). The measurements have provided a better understanding of the physical properties of CP-AFM tunnel junctions, which can be useful as the technique is applied to a broader range of molecular systems.

A new redox-resettable molecule-based half-adder with tetrathiafulvalene

Article Abstract:

A new redox molecule-based half-adder with tetrathiafulvalene (TTF) is reported, which employs electrochemical and chemical oxidations (NOP[F.sub.6]) as input signals and absorbances at 350 and 435 nm as output signals. This new molecule-based half-adder has shown reset capability by making use of the unique redox behaviors of TTF.
