Scientific Description
The Transmission Electron Microscopy and Atom Probe network (Microscopie Électronique en Transmission et Sonde Atomique - METSA) is a national network of 8 regional platforms comprising 13 TEMs (FEG instruments, aberration-corrected dedicated for Scanning TEM, analytical, spectroscopic, high resolution, environmental or in situ experiments, holography, tomography), 3 atom probes and 6 FIB / SEM (associated to the previous instruments). The 8 platforms are : IRMA: GPM, Rouen and CRISMAT, Caen; CEMES, Toulouse; IM2NP and CINAM, Marseille; CLYM, Lyon; PFNC-Minatec-CEA, Grenoble; IPCMS, Strasbourg; MPQ, Paris; LPS, Orsay. They own instruments with complementary performances and expertise. METSA aims at developing research in the largest field of Materials Sciences by means of advanced Electron Microscopy and Atom Probe analysis. Two applications per year allow users to propose projects which are examined by a program committee. METSA offers a support to training initiatives for TEM and AP to promote developments, new approaches and increasing expertise in a national frame regarding characterization of (nano)materials with high resolution techniques (TEM and AP). METSA is an actor at the French national as an aid to construct a national research strategy regarding characterization of materials by means of microscopy tools, in relationship with the Ministry of Research and Higher Education (national programs) and the CNRS especially.

Access to Electron Microscopes

METSA provides access to 'state-of-the-art' electron microscopes and atom probe to the scientific community through experiment requests evaluated twice a year by a Program committee constituted by independent experts.

Training

METSA supports actions regarding training on electron microscopy and atom probe from both theoretical and experimental points of views; it further correlates its action with the French Society of Microscopies (SFµ).

Equipment

The infrastructure offers an access to Advanced instruments based on TEMs or Scanning TEMs equipped with analytical accessories (EDX, EELS and imaging filters), optical correctors (probe and/or objective lens aberration correctors), monochromator, environmental configurations, biprisms, specific specimen holders (straining / heating / e-cells / tomography / cryo).1) JEOL ARM 80 - 200 kV (MPQ Paris): cold field emission, image Cs-corrector (0.075 nm), STEM (0.136 nm), EDX-SDD, GIF Quantum ER (0.26 eV), tomography, heating 1000°C / cooling liquid nitrogen stages, environmental cell (gas and liquid).2) FEI Tecnai 60 - 200 kV "SACTEM" (CEMES Toulouse): image Cs-corrector, STEM mode, GIF Tridiem, biprism for holography, Lorentz mode.3) FEI TITAN "Ultimate" 60 - 300 kV (PFNC CEA/LETI Grenoble): XFEG, monochromator for HR EELS (0.18 eV), probe and image Cs-correctors, STEM (0.07 nm), HREM (0.05 nm), GIF Quantum ultra-fast Dual EELS, corrected Lorentz lens, biprism for holography.4) FEI TITAN ETEM 80 - 300 kV (CLYM Lyon): image Cs-corrector (0.085 nm), environmental column (Pmax 25 mbar),Residual Gas Analyzing (RGA) system, heating stages 1000°C, STEM (0.136 nm), tomography, EDX-SDD Oxford Instruments, GIF Tridiem ERs (0.7 eV).5) Hitachi HF3300C "I2TEM" 60 - 300 kV (CEMES Toulouse): cold field emission, image Cs-corrector, biprisms for holography, Lorentz mode, STEM mode, Gatan Imaging Filter (GIF) Quantum ER (0.3 eV).6) JEOL 2100F 100 - 200 kV (IPCMS Strasbourg): probe Cs-corrector (0.11 nm), HRTEM (0.21 nm), GIF Tridiem, EDX-SDD, biprism for holography, heating 800°C / cooling liquid nitrogen stages, tomography.7) STEM NION USTEM 200 60 - 200 kV (LPS Orsay): dedicated STEM, ultra-stable stage, probe Cs-corrector, HR STEM (0.06 nm), HR EELS (0.27 eV).

Atom probes

Atom probes are based on the field ion microscopy where atoms from a "needle" cut into a given material are analyzed one by one by mass spectrometry and collected on a 2D detector allowing a tomographic reconstruction of the explored volume to be reconstructed at a nanometric and atomic level from both morphological and chemical points of view. Laser-assisted instruments allow non-ideally conducting materials to be studied. 3 atom probes are available:1) CAMECA LEAP 4000 HR (IRMA-GPM, Rouen): electric mode for metals, detection limit about 50 ppm, typical analyzed volume 150x150x500 nm3, mass resolution 1000 (FWHM), acquisition speed > 2 M atoms/min, T° 25K.2) CAMECA Lawatap + / Flextap (IRMA-GPM, Rouen): laser-assisted 1030/532/343 nm, ion microscopy; high voltage 15 kV, detection limit 4 1017 at/cm3, typical analyzed volume 80x80x200 nm3, mass resolution 2500 (FWHM).3) Imago LEAP 3000 XHR (IM2NP, Marseille): electric (250 kHz) and laser (532 nm) modes, detection limit 1018 at/cm3 typical analyzed volume 150x150x500 nm3, high voltage 15 kV, T+ 20K.

Focused Ion Beams and SEM

FIBs are a recent class of characterization tools made of the association of a scanning electron microscope (or column) with an ionic column. The ionic column delivers a beam of ions which allows to 'nano-machine' the matter for (i) preparation of dedicated samples for TEM or atom probe studies, (ii) nano-manipulation of nano-objects (contacting / straining experiments, (iii) tomography by serial abrasion of micrometric volumes. 6 FIBs or SEM are available (listed as they appear on accompanying pictures):1) FEI Helios 600 FIB (IM2NP Marseille): for preparation of atom probe tips.2) ZEISS NVision40 FIB (CLYM, Lyon): cross beam instrument; floodgun, two micro-manipulators, FIBICS generator, 3D-EDX and 3D-EBSD; Resolution SEM 1.1 nm, FIB 4 nm.3) FEI Helios 600i NanoLab FIB - Focused Ion Beam - (CEMES Toulouse): double column instrument equipped with a micro-manipulator for TEM lamellae preparation.4) ZEISS NVision40 FIB (IRMA-GPM, Rouen): cross beam instrument for preparation of atom probe tips; EBSD.5) FEI Strata FIB (PFNC Grenoble): double column instrument equipped with a micro-manipulator for TEM lamellae preparation.6) FEI XL30 Environmental SEM (CLYM, Lyon): for in situ heating (stages 1000°C and 1500°C) and environmental experiments (pressure up to 10 Torr; resolution 2 nm at 7 Torr); tensile stage up to 250 daN; low voltage STEM tomography ± 180°, wet-STEM.
