Nickelate thin films for electro-optical devices

Full project name:

Study of nickelate thin films and multilayers for development of novel electro-optical devices

Project Details

Transition metal oxides offer a vast variety of intriguing electronic phenomena, whose physical nature and emerging applications are among the hottest topics of modern research. Especial interest is attracted to thin films and multilayer heterostructures, whose functional responses can be tailored by controlling the crystal structure and interfaces. In this project, we will investigate influence of optical radiation on metal-insulator resistive behaviour in thin films and multilayer heterostructures of rare earth nickelates ReNiO3 with Re = Nd, Sm, Gd. The epitaxial films will be prepared by pulsed laser deposition and their microstructure will be varied using different substrates, film thicknesses and deposition/annealing conditions. Special attention will be given to polycrystalline thin films, p-n junctions composed of appropriately modified films and a few nm thick NdNiO3-SmNiO3 heterostructures with the metal-insulator transition near the room temperature.

Principle investigator

Current position: Senior Scientist, Department of Optical and Biophysical Systems, Institute of Physics of the Czech Academy of Sciences

Current research focus: Modern nano-scaled materials, namely thin epitaxial films of the perovskite oxides and metal-fullerene nano-composites. I am involved in the measurements of magnetic, piezo (electric) and optical properties of these materials

Previous expertise: Development of unique experimental techniques for measurements of the magnetic hysteresis and Barkhausen noise at controllable magnetization conditions

Role of MGML in the Project

Resistivity, magneto-resistivity, Hall, thermal conductivity/capacity measurements in a whole temperature range as well as at applied magnetic field.
