Adesida is an expert in the processing of semiconductors and other materials at the
nanometer-scale level and in ultra-high-speed
heterostructure field-effect
transistors—the sort of transistors used in
cell-phones,
fiber optics communications,
deep space communications, and other applications. His contributions have provided insights into the limits of advanced
lithography and other
nanofabrication techniques. He and his students continue to work in the areas of
nanoelectronics and high-speed
optoelectronic devices and
circuits. Recent work has focused on the development of devices and circuits in the key materials such as
indium phosphide and
gallium nitride utilized in high-performance
wireless, optical fiber communications, and high temperature applications. He has published over 350 referenced papers, has presented over 250 papers at international conferences, and has written many book chapters. ==Professional organizations and honors==
