Dr. Larkins' current research interests are focussed on the electronic properties of materials. Within this area he is actively pursuing research in applied superconductivity, thin film microelectronics and field-ion microscopy. He has ongoing national and international collaborative research projects with the Fritz-Haber Institute of the Max-Planck Society in Berlin, Germany and Xerox corporation's Palo Alto Research Center (PARC).

Among Dr. Larkins accomplishments are the first reported monomolecular tunnel-barrier Josephson junctions, first Metal-Langmuir-Semiconductor-Field-Effect-Transistor Integrated Circuits (MLSFET ICs) and the first reported observation of higher order inelastic tunneling in a tunnel diode with an ordered insulator. His more recent research efforts have led to the observation of aging effects and the establishing of aging time constants in high Tc superconductors. Present research includes investigation into the interaction of high Tc superconductors and ferroelectrics in the presence of an applied electric field (Superconducting Field Effect Transistors).

Dr. Larkins is currently responsible for teaching undergraduate Circuits, Electronics and Solid State courses and graduate level Applied Superconductivity, Electro Optic Devices and Circuits courses.
