FEI Themis Z Advanced Probe Aberration Corrected Analytical TEM/STEM

Location:

B66 MRL Materials Research Laboratory

The FEI Themis Z is and advanced analytical scanning/transmission electron microscope (STEM/TEM) from Thermo Fisher Scientific Company that operates between the electron energy of 60 to 300 keV with a Schottky electron emitter, an electron energy monochromator, and a 5th order probe spherical aberration corrector. The microscope is additionally equipped for chemical analysis using highly efficient and fast electron energy loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDS) systems.

This instrument will meet the research needs of electron imaging and chemical analysis in materials research. Specifically, the microscope enables imaging and chemical mapping in 2D and 3D at atomic or nanoscales by providing following research capabilities: 1) performing low voltage spectral analysis for molecules and single atoms using EELS, 2) conducting ultra-sensitive mapping of local bonding and oxidation states using EELS, and 3) analysis of composition and crystallographic orientation in 2D and 3D using EDS.

Scious 2 DualBeam FIB-SEM

Features:

  • Fast and easy preparation of high-quality, site-specific, TEM and atom probe samples using the Sidewinder HT ion column and EasyLift™ system for precise milling and in-situ sample manipulation and lift-out.  To achieve the high-quality results, final polishing with low-energy ions is required to minimize surface damage on the sample. The Sidewinder HT provides high-resolution imaging and milling at high voltages, but has also good low-voltage performance (to 500V), enabling the creation of high-quality TEM lamella.
