Electron Holography in Gaseous and Liquid Environment

Investigation of Effect of Electron Irradiation on Ionic Liquid Using Electron Holography

Ionic liquid (IL) has various attractive features and attract a great attention as new functional materials for applications. Recently, it has been reported that ILs were applied in scanning electron microscopic (SEM) observation because they do not vaporized even in vacuum condition [1]. Moreover, they can be also used as solvents and supporting films of nanoparticles for transmission electron...

Holography and transmission electron microscopy

The basic principles and methods of off-axis electron holography are presented and illustrated by means of three examples related to its application in high resolution electron microscopy and the investigation of electric and magnetic fields in thin specimens.

Aberration correction and electron holography.

Electron holography has been shown to allow a posteriori aberration correction. Therefore, an aberration corrector in the transmission electron microscope does not seem to be needed with electron holography to achieve atomic lateral resolution. However, to reach a signal resolution sufficient for detecting single light atoms and very small interatomic fields, the aberration corrector has turned...

Ferroelectric electron holography.

Ferroelectrics are increasingly important as materials in semiconductor technology, e.g. for building non-volatile memory chips. For optimisation of the properties of such devices, there is an urgent need for methods, which analyse the ferroelectric properties at nanometer scale. Furthermore, the basic understanding of the interaction of ferroelectrics with electrons in the transmission electro...
