TITLE: 

Transmission Electron Microscopy for Electromagnetic Field Measurement in Small Areas

Abstract:

Transmission electron microscopy can be used not only for microstructural observation, crystal structure analysis, and chemical state analysis of a specimen, but also for evaluation of electromagnetic field distribution inside and outside the specimen by detecting phase modulation or deflection of transmitted electrons. In this talk, I will introduce examples of analyses of “electron holography” and “Lorentz microscopy,” which are typical electromagnetic field measurement methods of transmission electron microscopy, and discuss future developments from the viewpoint of metrology informatics.
