    Thin Films Laboratory

    • About

      The Service of Thin Films has been created to offer to the researchers the capability of fabrication of complex oxides thin films and heterostructures combining oxides and metals.

      The deposition techniques are pulsed laser deposition (PLD) for oxides and sputtering for metals. Currently there are two PLD set-ups installed, and in short time both systems will be connected to a chamber with several sputtering units. PLD is a physical vapour deposition technique that uses ultraviolet laser radiation to vaporize material that is transferred to the substrate. The plot in Figure 1 is a sketch illustrating a PLD set-up.

      The pulsed beam of an ultraviolet laser (usually an excimer) is focused on a ceramic target placed in a vacuum chamber. The combination of pulsed irradiation, high photon energy, and high energy density can cause the ablation of the material. Ablation refers to the etching and emission of material under conditions totally out of the equilibrium. The plasma created expands fast along the perpendicular direction of the target (see the photography in Figure 2). A substrate is placed front the target, and inert or reactive gases are usually introduced during the deposition process.

      The technique is very suitable for oxides, and compared with other techniques is particularly useful to obtain films with complex stoichiometry and to grow epitaxial films and heterostructures. Moreover, PLD is highly versatile to optimize the deposition conditions of new materials, and the films can be grown in relatively fast processes. These characteristics favour the use of the technique by research groups having interest in different materials.

    ABOUT

    About

    vega

    The ICMAB Spectroscopy Service was created with the main objective to provide centralised equipments and installations mainly to the research ICMAB groups though the service is also opened to external users. The priority of this service is to offer the highest levels of technology and quality to satisfy the requirements of the research lines currently underway in our institute. The currently equipments available are: EPR, RAMAN, UV-Vis-NIR, FT-IR and Luminescence spectrometers. For EPR and RAMAN equipments highly qualified technical staff is employed. The rest of the equipments are mainly used on a self-service regime. Three types of spectroscopy techniques have been carried out: a) Molecular spectroscopy: The systems available in our laboratory allow analytical and physic-chemical studies of organic and inorganic molecules (in solid or liquid state) in the ultraviolet, visible and infrared energy range. b) Electron Paramagnetic Resonance: The EPR allows to detect and study transient and stable paramagnetic species such as free radicals, over a very wide range of temperatures.

      TGA-DSC/DTA

      The simultaneous TGA-DSC/DTA analyzer allows the measurement of weight and DSC (heat flow)/DTA (differential thermal analysis) signals as a function of temperature and time. It is used for monitoring chemical reactions, thermal stabilities, solvent evaporation and reduction and oxidation of materials under different gases among other studies. The sensitivity of the balance is 0.07 micrograms. The furnace can operate from room temperature to 1400oC. The analyzer may work in several atmospheres such as oxygen, air, argon and hydrogen (diluted at 5% in Ar), at ambient pressure and with using typical flow rates of 70 cm3/min.

      DSC

      The differential scanning calorimeter Perkin Elmer (power compensation) measures the energy absorbed and released when a sample is heated, frozen, or kept at constant temperature. Experiments can be made in the range of temperatures between 110 and 950 K. DSC is very useful to determine fusion or decomposition temperatures, phase transitions in crystals and amorphous solids, identification of polymorphs and also permits the identification of the molecular conformations as for example single polymer chain folding among others. With this equipment, very small amount of sample is needed (1-2 mg ) to have reliable results.
