My research centers on making and understanding the physical properties of materials applicable to nanomolecular devices. The challenge lies in assembling molecules on surfaces and understanding the behavior of 1-, 2- and thin 3-dimensional (1-, 2- and thin 3-D) materials. The ultimate goal is to build surface structures with special optical and electronic properties, such as reversible electrochromic or photovoltaic behavior.
Thin 3-D layered materials are formed by stacking simpler pieces, i.e. repeated electrosynthesis of surface-bound polymers using different materials. The oxidative coupling of aromatic amine monomers leads to polymeric materials that are oxidatively reversible, semiconductive, and have intense vibrant color changes. We use an Electrochemical Quartz crystal Nanobalance (ECQN) to help determine the mechanisms of film deposition in conjunction with standard electrochemical techniques such as cyclic voltammetry and chronopotentiometry. Thin-layer Spectroelectrochemistry helps us determine what intermediates are formed in the process. We also are using Electrochemical/Electrospray/Mass Spectrometry to understand the mechanisms ion transport in and out of films, as well as for the basic understanding of electrochemical mechanisms. To date, we have developed molecule-based diodes, organic-based Schottky diodes, organic-based Schottky and Silicon-gated Thin Film Transistors (TFT). We have fabricated thin organic films in low-modulus stress sensors.
