Background
Dr. Sudarshan's specializations and research interests include:
- Novel techniques of growth of silicon carbide (SiC) bulk and epitaxial films
- Surface modification to produce porous SiC
- SiC material and device processing – wafering, surface polishing, oxidation, mask technology, dopant diffusion, and metalization
- Fabrication and characterization of SiC high power Schottky and pn diodes
- Novel defect characterization methods for wide bandgap semiconductors. High field effects in SiC-based electronic materials and devices
- High power solid-state switches; electron emission from thin films, as cold cathodes, for applications in field emission displays
- Microspacer insulation for flat panel displays
- Solid, liquid and gas insulated systems for high voltage power apparatus, underground power cable, overhead transmission systems and pulsed power systems
- Surface flashover of solid dielectrics and photoconducting materials in high vacuum and compressed gas systems
- Fast high voltage and current diagnostics, and low light level imaging; electric field studies using numerical techniques
- Insulator degradation and aging, coronas and arcs, power system protection.
