Work function is one of the most fundamental properties of materials. We have found that it can be modulated by interaction with electrically neutral molecules. The quantitative relationship describing this interaction is similar to the Nernst equation which is the operating principle of Ion-selective electrodes.
Special skills required are electrochemistry and instrumentation analysis.
Higher Order Chemical Sensing Arrays. This research area builds on the work function research described above. The aim is to fabricate in silicon arrays of chemical sensors in which more than one transduction principle is employed. The research involves design, fabrication and testing of integrated circuits used for this purpose, selective layer deposition, encapsulation and packaging. The special skills required in this work include device fabrication and materials science.
