Ajay Karakoti

Ajay Karakoti is a Co-Principal Investigator of the ANGEL project, where he leads the synthesis of foam targets for EUV source development and drives surface science investigations into the degradation of multilayer mirrors in EUVL systems. His work focuses on precise synthesis of materials by controlling various factors that affect the size, morphology and textural properties of materials. His research unravels the effect of local environments on the activity and stability of materials specifically engineering redox-active materials. By precisely controlling surface chemistry, oxidation states, and defect structures, he uses advanced in-situ spectroscopic techniques—including cryo-XPS—to decode fundamental interfacial processes. His research not only advances the understanding of redox cycling for heterogeneous catalysis and sustainable energy applications but also underpins innovations in nanotechnology and resilient materials.
