Welcome to the website of the lab of Charles H. Ahn, William K. Lanman Jr. Professor of Applied Physics, Physics and of Mechanical Engineering and Materials Science

 

Home

The Ahn Lab is a research group affiliated with the Department of Applied Physics at Yale University and the Center for Research on Interface Structures and Phenomena (CRISP), a National Science Foundation Materials Research Science and Engineering Center (NSF-MRSEC). The lab investigates the electronic and magnetic properties of strongly correlated oxide materials.

Lab Openings

The Ahn laboratory is currently accepting applications for post-doctoral positions. Interested candidates may send a CV to halima.chahboune@yale.edu
