UltramicroscopyAbstract
A Kossel microdiffraction experimental setup has been developed inside a Scanning Electron Micro-scope for crystallographic orientation, strain and stress determination at a micrometer scale. This paper reports an estimation of copper and germanium specimens heating due to the electron beam bombardment. The temperature rise is calculated from precise lattice parameters measurement considering different currents induced in the specimens. The spatial resolution of the technique is then deduced.
