Our research is centered around understanding the effects of defects and microstructure on the physical properties of functional oxides. Using continuum level computational and experimental approaches, we try to reveal the mechanisms by which defects and interfaces impact the physical properties and at what magnitude this occurs. Such knowledge is the key to design and fabricate structures in various geometries for specific engineering applications. The applications governed by such phenomena encompass macro- and micro-scale capacitors for electric energy storage, non-volatile solid state memories, nanoscale devices and electrooptical thin films. Our groupís research covers:
Ferroelectric-semiconductor interfaces, resistive memory action of such systems.
Phase transitions in functional oxides and artificially grown multilayers/superlattices.
Effect of defects on thermodynamics and phase transitions of crystalline materials.
Growth of ferroelectric and multiferroic films using chemical precursor methods and their characterization.
Electrocaloric effect in ferroelectric solid solutions and its applications.
New: We study ways to enable electrical control of magnetic order in confined nanoscale ferromagnets using micromagnetic simulations based on the Landau-Lifshitz-Gilbert equation coupled with Maxwell relations. Check our simulation result by clicking here to see the switching the of the vortex state in a 55 nm diameter permalloy disc from counter clockwise to clockwise direction upon application of an electric pulse to the system. The entire process takes about 3 nanoseconds.
New: A recent interest of our group is about ferromagnetic/ferroelectric interfaces that are vital to understand for multistate solid state nanoscale non-volatile memory structures. In this context, we analyze electrodynamics of such interfaces in confined dimensions and demonstrate the possibility of electric field control of magnetic order, a highly desired outcome due to problems (bulky components, problems with confining magnetic fields etc.) with applying magnetic fields to nanoscale magnetic memory devices. We are also interested in materials for devices designed to allow spin-polarized tunneling that find use in spintronics.
