College of Engineering

Principal Investigator of Chemical and Bio-Sensing Program.Developed a unique low-cost electrostatic charging technique for self-assembly and surface functionalization of Multi Walled Carbon Nanotubes (MWCNTs).

Developed unique functionalization techniques for the self-assembly of conductive polymers at molecular levels on insulating surfaces. Photo-generated carrier transport was established using tools such as AFM, PL, Pulsed Laser and a High Speed Digital Storage Oscilloscope.Kinetics of the photoexcitaions was established based on data analysis of fluctuations observed in the generated photo-current.PublicationsOptical and electrical features of surface ordered regioregular polyhexylthiophene, V.

Involved in research activities at Samtel Research Center, IIT Kanpur for the development of electronic displays.Developed and taught (Semesters I and II 2003-2004) a new course in 'Display Technologies and Materials'. The course provides a complete overview of flat panel display technologies along with fabrication techniques, materials aspects, and characterization of displays. .

Development of 5' Colored VGA Flat Panel Display based on Field Emission. Assembled thin film deposition units, high vacuum measurement system for cathodoluminescent studies. Fabricated thin edge emitters using arc deposition technique for carbon nanomaterials. Achieved synthesis, deposition and photo-lithographic patterning of cold cathodes for triode devices.

Doctorate thesis work on Optimization and Characterization of Blue Light Emission from Zinc Oxide doped Tungsten Phosphor and Implementation of the Zinc Oxide Tungsten Phosphor in a Lateral Edge Well-Type Field Emitter Device for Field Emission Display purposes. The research was focused on developing Field Emission Displays for low voltage blue light emitting phosphors. A low voltage blue light phosphor of zinc oxide and tungsten was fabricated and successfully integrated with field emission devices having later edge design. The research was successfully completed by establishing:(a) Techniques for phosphor deposition and luminescent characterization,(b) Fabricating thin edge emitters using arc deposition technique for carbon nanomaterials(c) Technology for the integration of thin-film phosphor with a lateral edge field emitter device,(d) Testing, characterization, and emission of blue light emission from the devices at low voltages.PublicationFabrication and Characterization of a Monolithic Thin-Film Edge Emitter Device with Zinc Oxide Tungsten Based Thin-Film Phosphor’, J.
