Single Molecular Transistor
A single molecular transitor works on the basis of quantum tunnelling, with a molecular species as the island located between the source and drain electrodes, backed by a gate. We have engineered the geometry, in terms of gate structure and coverage to the island and island to design sensors. Such structures seem to offer extreme detection densitivty for application like: (i) charge detection, (ii) presence of impurity atom, (iii) chemical and gas sensor, (iv) detection of toxic molecules, (v) humidity sensor and (vi) DNA/RNA detection. Details can be found in the publications.
