Electron Holography of Organic and Biological Materials



Electron holography offers the advantage of high resolution imaging of electric and magnetic fields, which is rarely achieved by other microscopic techniques. The variety of scientific tasks investigated by electron holography extends from subatomic-resolution imaging of inorganic crystal structures up to morphological studies of polymers or biological samples by making use of subtle differences in their chemical composition or density. In this paper, we discuss basic prospects and applications of holography in the field of organic semiconductor devices and biological samples, as well as in polymer science.
