Electron microscopy

The ICN2 Electron Microscopy Unit focuses on the use of electron microscopy techniques for research and applications in nanoscience and nanotechnology. The main objective of the Unit is to provide scientific-technical support to the ICN2 research lines and to external scientists and private companies, as well as to develop and implement new techniques. The laboratory has active collaborations with other research institutions and is increasingly involved in European networks, such as the NFFA project. It offers researchers and students a wide range of processing services to help them carry out their research activities.

ELECTRON MICROSCOPES

ELECTRON MICROSCOPES

FEI Magellan 400L XHR SEM

The Magellan 400L is a Field Emission Scanning Electron Microscope equipped with a newly developed electron column with a monochromator, UC (UniColore) Technology. This microscope features excellent capabilities in the more traditional high energy (15-30 kV) SEM and STEM imaging, but also has an outstanding performance at low beam energies with subnanometer resolution for unmatched surface sensitive imaging.

The recently attached X-Max Ultim Extreme EDX (Oxford Instruments) converts this microscope in a unique tool, as it allows an ultrafast compositional nanoanalysis and mapping with an unprecedented sensitivity and energy resolution, even for light elements such as lithium.

FEI Quanta 650FEG ESEM

The Quanta 650 FEG is a versatile Field Emission Scanning Electron Microscope which provides high resolution imaging at high vacuum, low-vacuum and also extended vacuum (environmental SEM or ESEM) for the characterization of all type of samples (conductive, non-conductive and wet samples) and performing in-situ dynamic experiments. This microscope features a large chamber with the capacity of analyzing up to 16 samples at the same time and compatible with 8 inches wafers.

FEI Tecnai G2 F20 S-TWIN HR(S)TEM

The FEI Tecnai G2 F20 is a 200kV field emission gun (FEG) high resolution and analytical TEM/STEM. It is ideal for applications requiring high coherency, high brightness at high magnification, or small focused probes. It is a versatile and flexible microscope and combines high performance in TEM and STEM modes with ease of operation in a multi-user research environment.

Thermo Fisher Scientific Helios 5 UX FIB

The FIB Helios 5 UX is a high-performance focused ion beam (FIB) scanning electron microscope (SEM) system designed and manufactured by the company Thermo Fisher. This advanced equipment is used for a wide range of applications, including materials science, nanotechnology, and semiconductor analysis.

The FIB Helios 5 UX is equipped with a high-resolution SEM (Elstar extreme high-resolution field emission) that provides images with a resolution of up to 0.8 nm, allowing researchers to see details at the nanoscale. Additionally, the system includes an ion column (Phoenix Ion Column with superior high-current and low-voltage performance) that can be used to modify, manipulate and prepare samples, making it an ideal tool for creating high quality TEM lamellas at low voltage.

Thermo Fisher Scientific Spectra 300 (S)TEM

The Thermo Fisher Scientific Spectra 300 (S)TEM is a double-corrected transmission electron microscope, operated in either TEM or STEM mode, equipped with an ultra-high energy resolution field emission gun (X-FEG) and a monochromator (Ultimono). It is ideal for applications requiring the highest attainable spatial and energy resolution.

The Spectra 300 microscope is a joint initiative of several institutions of international prestige that have established a collaboration agreement, specifically the ICN2, CSIC (and its ICMAB-CSIC center), UAB, ALBA, with contributions also from BIST and Microsoft.

SAMPLE PREPARATION

SAMPLE PREPARATION

High Vacuum Sputter Coater - LEICA ACE 600

The sputter coater Leica EM ACE600 is a high vacuum film deposition system that produces very thin, fine-grained and conductive metal and carbon coatings for highest resolution analysis, as required for FE-SEM and TEM applications. It can be configured for the following methods: Sputtering Pt or Au and Carbon thread evaporation. Coating thicknesses range from 2 nm to tens of nanometers.

Optical Microscope - LEICA DM 2700 M

The Leica DM 2700 M optical microscope combines high-quality Leica optics with state-of-the-art universal white light LED illumination in both transmitted and reflected light modes. It is an ideal inspection tool for all kinds of routine inspection tasks in metallography, materials quality control, earth science and research. Our system has 5X, 10X, 20X and 50X achromatic objectives with a 10X eyepiece that allows us to acquire images at 50X, 100X, 200X and 500X magnification.

Plasma cleaner – Fischione 1020

The Fischione 1020 plasma cleaner automatically and quickly removes organic contamination (hydrocarbon) from electron microscopy specimens and specimen holders. The high-frequency plasma is generated with a gas mixture of 25% oxygen and 75% argon

Precision Diamond Wire Saw - Well 3242

The Precision Diamond Wire Saw Well 3242 produce smooth, sharp-edged surfaces on almost any cut material. The cutting tool employed is a stainless steel wire with diamonds embedded into the surface of the wire. It uses gravity and/or weights as the method for achieving and maintaining consistent feed rates. Also, it has a continuously variable wire speed adjustment. A slotted table enables the operator to position the sample in both axis while the sample holder rotates throughout 360 degrees for proper orientation of the proper cutting axis.

Precision Disc Saw - Struers Minitom

The low-speed precision disc saw Minitom can be used to section all types of mineralogical and ceramic specimens. The cutting speed is continuously variable as well as cutting pressure. Many sample holders are available to cut all types of samples.

Precision Ion Polishing System - Gatan PIPS (model 691)

The Precision Ion Polishing System (PIPSTM) is a precision ion polisher designed to produce high quality TEM specimens with minimal effort. Emphasizing ease of use, the PIPS features full manual control, making it reliable to operate and easy to maintain.

Precision Polishing System - Allied Multiprep (TM)

The MultiPrepTM is a precision polishing system that enables precise semiautomatic sample polishing of a wide range of materials for microscopic (optical, SEM, FIB, TEM, AFM, etc.) evaluation. Capabilities include parallel polishing, angle polishing, site-specific polishing or any combination thereof. Dual micrometers (pitch and roll) allow precise sample tilt adjustments relative to the abrasive plane. A rigid Z-indexing spindle maintains the predefined geometric orientation throughout the grinding/polishing process.
