1. Optical characterization of wide band gap materials by spectroscopic ellipsometry
Abstract : Spectroscopic ellipsometry has been employed in the study of wide band gap materials. Ellipsometry is based on the study of changes in the polarization state of light upon reflection on a surface. READ MORE

2. Physical Properties of Ternary Metal Oxides and Carbon Nanomaterials Under Pressure
Abstract : Found in nature or synthesized, materials present amazing properties such as superconductivity, super-hardness, lightweight, or high-energy-density, among others. All these properties can be used in our benefit to improve or develop new applications. READ MORE

3. Development and Characterisation of SiC Based Sensors for Harsh Environments
Abstract : The introduction of chemical gas sensors in our environment is a process that started many years ago. However, although the process has been rather slow over the years, the interest for chemical gas sensors is rising due to the growing environmental awareness. READ MORE

4. Tailoring of Contacts on Silicon Carbide - Procedures and Mechanisms
Abstract : Silicon carbide (SiC) exhibits very good electrical, thermal, chemical and mechanical properties which make it suitable for the next generation of wide band gap electronic devices, where silicon (Si) cannot be used due to its limitations with respect to the mentioned properties. Nickel (Ni) and Tantalum (Ta) are among the metals used for the contact formation. READ MORE

5. Atomic scale modeling of ordering phenomena in inorganic clathrates
Abstract : Ordering phenomena in materials often have a crucial impact on materials properties. They are governed by the competition between entropy and energy. Accordingly simulating these aspects requires the construction of models that enable an computationally efficient exploration of the relevant configuration space. READ MORE
