ADVANCED IMAGING AND DIFFRACTION TOOLS FOR TRANSMISSION ELECTRON MICROSCOPY
TEM NANOSCALE STRAIN MAPPING – AutoSTRAIN
TopSPIN Strain combines Precession Electron Diffraction (PED) with automated strain mapping and analysis of diffraction patterns by comparing unstrained and strained areas in the same crystalline sample (Patent Pending).
This technique gas the unique advantage of achieving high precision (0.02%) and a spatial resolution down to 3 nm (specimen dependent).
