Description
This programme centres on the investigation of advance ceramic materials and the possibilities offered by energy-filtering electron microscopy to understand and solve technological problems encount...ered with these new materials. Image formation and energy selection are illustrated by BCU views of the microscope's interior and 3D animation. To end with, two developments in technology are addressed briefly, beginning with a description of a 1.2MeV Transmission Electron Microscope which can give atomic resolution; this is followed by an examination of the principles of Scanning Tunneling Microscopy as a means of 'seeing' surface topography on an atomic scale.
