ADVANCED IMAGING AND DIFFRACTION TOOLS FOR TRANSMISSION ELECTRON MICROSCOPY

NANOSTRUCTURES

Revealing nanoparticles, nanowires and multilayer texture at nm level helps to understand and predict their (electrical, transport, optical) properties. Orientation and phase mapping with ASTAR sheds light to their texture and phases, while 3D electron diffraction tomography may reveal their detailed crystal structure. Strain maps in multilayers help monitor structural properties.
