Surface Analysis Unit

Description

Surface Analysis Platform at the CIC energiGUNE is a laboratory equipped with state-of-the-art surface specific experimental techniques that can be used to analyze solid state materials, including thin films, powders, as well as polymers and, in some, cases even liquids.

Surface composition, electronic and atomic structure can be probed by combination of several complementary spectroscopic, diffraction and microscopic techniques: photoemission spectroscopy (XPS and UPS), Auger electron spectroscopy (AES), scanning Auger microscopy/scanning electron microscopy (SAM/SEM), Raman spectroscopy, near-field scanning optical microscopy (NSOM), tip enhanced Raman spectroscopy (TERS), ambient pressure scanning probe microscopy (STM and AFM).

The services are provided for research groups within the center as well as to the external users such as research centers or other public organizations, but also to private companies or individuals.

Instrumentation

SPECS MULTI TECHNIQUE SURFACE ANALYSIS SYSTEM FOR HIGH RESOLUTION XPS, AES, SEM/SAM, ISS AND DEPTH PROFILING

Multi Technique UHV Surface Analysis System for XPS, AES, SEM/SAM and depth profiling with high space and energy resolution on the different types of conducting and not conducting samples ranging from single crystals to polymers and powders. The system has a unique combination of methods for in-situ sample preparation and treatment provided by four e-beam evaporation sources in the Preparation Chamber, a high pressure cell and electrochemical cell. The analytical part of the system is a SPECS GmbH setup based on the hemispherical analyzer PHOIBOS 150, twin anode Al/Ag- X-ray source with monochromator FOCUS 500, fine focus electron gun with Schottky emitter for SEM/SAM, flood gun FG15/40 for charge compensation and small spot ion gun IQE 12/38 for ion treatment and precise depth profiling.
NANONICS & RENISHAW - NANONICS MULTIVIEW 2000 TERS WITH RAMAN SPECTROMETER

NANONICS MULTIVIEW 2000 TERS with RAMAN SPECTROMETER. SNOM microscope in transmission, in collection and reflection, atomic force microscope (AFM), non-contact mode, acoustic AC, LFM, MFM, Confocal Raman microscope and confocal microscope and optical.

This equipment allows the non-destructive characterization of nanostructures and interfaces in the materials used in batteries and supercapacitors via the study of chemical and physical properties with optical spectroscopy. This techniques will deliver advanced information of chemical bonds and other variables of the molecules. Raman spectroscopy is an important technique for the microscopic study of ceramic and polymeric materials that are commonly used as electrodes and electrolytes in batteries and supercapacitors.
