ASTAR - Automatic phase and orientation mapping for TEM
ASTAR can easily be retrofitted to any (old or new) 100- 400 kV TEM TEM based technique similar to EBSD for SEM (with much higher resolution details) Perform detailed orientation maps (Orientation resol < 1º , < 5 nm step size) for metals,
ceramics , semiconductors and any type of diffracting material, any crystal symmmetry,
no sample preparation Perform detailed crystal phase maps (resolution < 5 nm -TEM FEG , < 25 nm - LaB6 TEM) Ultra-fast data adquisition (< 5 min ) (eg 5x 5 microns, 500 x 500 points) with CCD camera Scanning in combination with precession for accurate orientation and phase maps Generation of simulated ED patterns (templates) for all possible crystal symmetries
and comparison with experimental ED patterns via cross – correlation techniques. to
retrieve accurate phase and orientation maps (any crystal symmetry)
