Understanding the influence of the surrounding environment on the sliding friction between two solid surfaces in liquids is of utmost importance for applications to MEMS/NEMS or colloidal systems as well as to shed light on the dynamics of formation and rupture of single contact junctions. In this project we aim to perform an experimental investigation of the mechanical properties of contacts formed by sharp silicon tips on solid surfaces with different degrees of complexity using friction force microscopy. The sample surfaces will be exposed to electrolyte aqueous solutions and to polar and nonpolar solvents with varying viscosities. The different interaction potentials will be quantitatively reconstructed from the time variations of the friction forces acting on the tip with original numerical techniques. The results so obtained will be compared to complementary information obtained with dynamic AFM modes.
At the Faculty of Physics and Astronomy in the Friedrich Schiller University and in collaboration with the group of Dr. Ronen Berkovich (Ben Gurion University of Negev, Israel).

Materials Physics Center (CFM, CSIC-UPV/EHU) in Donostia-San Sebastián, (the Basque Country, Spain) is currently seeking for bright, highly motivated PhD candidates who are willing to work in an intellectually stimulating environment to develop cutting-edge training and research on Materials Science, exploring physical and chemical properties of advanced materials, nanostructures and nanodevices, either theoretically or experimentally. They will have access to the most advanced techniques in the field and develop industry-transferable skills.
Approximately 25 applicants will be shortlisted and invited for a 2-days visit to CFM in May, with their travel and accommodation expenses fully covered. Personal interviews will be held and the candidates will have the opportunity to discuss the research projects.
From the interviews, 7 candidates will be selected and granted full studentships.
CFM is focused in the following research areas:
- Chemical Physics of Complex Materials
- Electronic Properties at the Nanoscale
- Polymers and Soft Matter

Graphene has been praised as a new electronic material; but if it is to be used for high-performance nanoelectronics, not only new device processing are required to preserve graphene in its pristine state but also a new electronic paradigm is needed to take full advantage of graphene unique properties.
This project focuses on the development of graphene/boron nitride (BN) epitaxial hetero-structures to realize ultra-thin body tunnel field effect transistors (UB-TFETs), based on epitaxial graphene nanoribbons on SiC (EG). With a structure isomorph to that of graphene, hexagonal BN is considered the best interface dielectric for graphene and we have recently demonstrated high quality epitaxial growth of BN on EG by metalorganic vapor phase epitaxy . EG nanoribbons have exceptional transport properties characterized by a quantized ballistic conductance even at room temperature . These structures will be used to study fundamental questions related to the graphene ground state at charge neutrality, that has so far remained elusive, and, ultimately, to enable a new generation of devices.
This project combines the expertise of the hosting group, with 18 years experience in developing graphene for electronics, the nitride research team at UMI – Metz, the 2D material microscopy experts at ONERA – Paris and the graphene surface group at CNRS/ Institut Néel in Grenoble.

As responsible for the daily activities in the BALTAZAR laboratory you will conduct research using our state of the art laser based ARPES system for high resolution and time-resolved ARPES. The system has recently been upgraded to provide photon energies up to 30 eV with ~20 meV resolution and time resolution to below 100 fs which enables unique research capabilities. Apart from your own research you will also assist Postdocs, Ph.D. students and visiting scientists with their experiments.
The scholarship fund of the Society of Vacuum Coaters Foundation is entering its 16th year. Since inception, we have issued scholarships and travel awards totaling over $280,000 to students from 22 countries around the world. We continue to seek qualified and worthy students and ask for your assistance in finding great applicants. In addition, we have a new “Technical” scholarship that launched in 2018 to further the education of those already working in the vacuum coating industry.
The SVC Foundation will award several scholarships ranging from $2500 to $5000 in early 2019 for the 2019-2020 academic year. The scholarship is open to any student currently enrolled or entering an accredited academic program related to the vacuum coating technology field; including chemistry, chemical engineering, materials science, electrical engineering, physics and related subjects. Preference is given to students who are expressly interested in vacuum coating technology and currently engaged in studies and research relating to vacuum coatings. Please pass this information on to exceptional students. SVC members whose children or relatives are pursuing studies related to vacuum science are encouraged to apply.
This new scholarship introduced in 2018 is offered to those already working in the field of vacuum coating technology. It is intended to help further the education of technical staff by providing financial support for the many educational opportunities the SVC offers. It may cover the cost of books, on-line classes, or even travel and tuition for educational classes at the 2019 SVC TECHCON in Long Beach, California (April 27-May 2). Please forward this information to your colleagues that could benefit from additional education in their field.
Deadline for applications is December 3. Applications and additional information are available online at the SVC Foundation website:
