Equipment: Hitachi S-5500 SEM equipped with STEM

Description

This instrument was purchased in 2008.  The S-5500 is an in-lens field-emission gun scanning electron microscope with a 0.4 nm lateral resolution at 30 keV.  It is also equipped with a dark-field detector and a bright-field detector for scanning-transmission electron microscopy (STEM) imaging. The BF/DF dou-STEM detector allows simultaneous observation of BF and DF STEM images. The acceptance angle of the DF STEM signal is variable and can be selected from the menu. An energy dispersive spectroscopy detector (Bruker EDS Quantax 4010) is also installed for elemental stoichiometric ratios, multiple elemental line scanning, and 2-dimensional mapping. The topography and composition of a sample is also complimented with an automated YAG backscattered electron detector.
