Research Nuggets

Dr. Rajaputra started his research career by working on ferroelectric and magnetic oxides and two phase composites. Later he continued his work in to transition metal oxides showing colossal magneto resistance (CMR) and charge ordering. After he moved to University of Kentucky in 1999, he started working on sensors and nanoporous oxide films. His current research interests are Synthesis and Characterization of nanoscale materials, Design and fabrication of nanoscale hetero-junction devices, Hybrid organic-inorganic devices and Sensors. The underlying theme of his research continues to be structure-property correlations in materials. Some of his current research projects are listed below.

Template free fabrication of nanoporous oxide films

Fabrication of metal oxide nanowires and nanotubes

Novel hetero-junction thin film opto-electronic devices

Fabrication and characterization of Nano-porous CdS and CdTe films by a soft chemistry route.

Novel method for fabricating semi-conducting nano fibers.

Fabrication of magnetic nanostructures and study of their switching behavior and dynamics.

Design and fabrication of nanoscale hetero-junction devices
