Prof. Ramesh's
research centers on the following four areas:
Metal Oxide
Thin Film Growth and Characterization
Metal oxide thin
film deposition and processing for microelectronic, optical and high-frequency
applications; pulsed laser deposition and chemical vapor deposition;
oxide thin film heterostructures; growth mechanisms and defect structures;
structure-property-processing interrelationships; ferroelectric and
magnetic oxide thin film heterostructures; and integration of Si and
GaAs for device applications.
Transmission
Electron Microscopy
Application of
TEM techniques to solving materials problems: high-resolution atomic
imaging of defect and crystal structure in oxides; analytical electron
microscopy and micro-diffraction techniques; and imaging of domains.
Materials Processing
for Devices
Nano-fabrication
technologies; novel physical phenomena in electronic, magnetic, and
photonic materials with shrinking dimensions; and dry etching technologies
for device fabrication in metal oxide electronic and photonic materials.
Information
Technologies
Non-volatile information
storage technologies: ferroelectric random access memories; integrated
optical devices for information processing and storage; thin film magnetic
and magneto-optic materials for recording media and heads; integrated
giant-magnetoresistive oxides for sensors and heads; "smart" thin film
for sensors and actuators; and technology development and marketing.
