FIB / SEM / ECS Systems Laboratory

This laboratory aims to provide the student with an insight into the capabilities of combined SEM, Focused Ion Beam systems in the areas of imaging, machining, material deposition and chemical analysis. Students will gain practical experience in the use of FIB systems for both patterning and characterisation at the nano scale. The session will cover the principles, operating characteristics and practical applications of the system.
