Research Areas

Electronic Ceramic Materials, specially ferroelectric materials.
- Dr. Guha introduced a new technology for chemical doping of niobium in barium titanate.
- He proposed a material having very high dielectric constant of about 105.
- He also found out the exact dopant concentration of Nb for which a material undergoes semiconductor to insulator transition.
- Work is now bing done on processing and characterization of electronic ceramic materials with improved PTCR (positive temperature coefficient of resistance) properties, sensor materials, actuators etc.
