Carmichael Research Lab
A particular area of focus is intrinsically stretchable devices, in which the active device area itself can withstand tensile strain
(A video of a light-emitting electrochemical cell being stretched can be found here .
We also work on developing new self-assembled monolayers (SAMs) and studying their transport properties in molecular tunneling junctions using a eutectic gallium-indium (EGaIn) top electrode. We have established a variety of new SAMs to study that are made from dithiophosphinic acid derivatives (DTPAs). DTPAs chelate to the underlying gold substrate to enhance charge injection. Unlike other chelating adsorbates, however, chelation of DTPAs can be easily disrupted by grain boundaries and step edge defects of the underlying gold substrate.
Consequently, another aspect of our work is developing chemical-mechanical polishing to prepare nearly atomically smooth gold surfaces for SAM formation.
