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.
