DIPC - UPV/EHU PhD STUDENT GRANTS
ZABALDUZ PROGRAMME
The Donostia International Physics Center (DIPC) in collaboration with the University of the Basque Country UPV/EHU is currently accepting applications for PhD students under the ZABALDUZ programme. This is a unique opportunity for highly motivated students in physics or related fields, to develop a research career joining some of the DIPC high-profile research teams.
The duration of the appointment will be initially limited for 1 year with rolling renewal up to a maximum of 3 years.
Candidates must hold a master's degree in physics, chemistry or material science.
More information on these positions can be obtained by contacting: [log in to unmask]
Deadline for applications is scheduled for September 26th.
Details on the current ZABALDUZ call can be found on the UPV/EHU webpage (only in spanish and basque):

The available PhD research projects are described below.
PhD OPENINGS
Implementation of non-adiabatic effects in the interaction of metal surfaces with atoms and small molecules
Contact person: Dr. Maria Blanco Rey ([log in to unmask]).
UPV/EHU supervisor: Dr. J. Iñaki Juaristi
Heterogeneous catalysis is a recurrent motivation in surface science. Many molecules that are stable in their gas phase, e.g. H2 or O2, show a reduced binding energy upon interaction with a metal surface. We propose to study the dynamics of such interactions. First principles calculations based in the Density Functional Theory (DFT) are a useful tool in this field, since they provide with accurate quantitative information in problems of high sensitivity towards multidimensionality, as it is the case of molecule-surface interactions.
Nevertheless, usual DFT calculations do not feature non-adiabatic effects. These are relevant when a non-negligible amount of energy is passed from the molecule onto the surface, which causes vibrational (phonons) or electronic [electron hole (e-h) pairs] excitations. Non- adiabatic effects are usually introduced “a posteriori” in the dynamical analysis using a number of parametrizations. In the proposed project, we will explore several implementations of these energy loss channels within first principles calculations. We will also develop simple models of energy loss by e-h pairs in typical scecnarios, using models (e.g. jellium) of the surface electronic structure.
Theoretical study on the molecular adsorption and self-organization on substrates of different nature
Contact person: Dr. Pepa Cabrera-Sanfelix ([log in to unmask]).
UPV/EHU supervisor: Dr. Daniel Sanchez-Portal
This project is focussed on the adsorption of small organic molecules and other molecules of technological interest, such as water and CO, on substrates of different nature, well metallic, ionic or graphitic. In one side, the project will be focussed to investigate the possible electronic structure modifications of those substrates due to the interaction with the adsorbates. On the other side, it is of great interest to explore how this modifications affect to the self-assembly of the adsorbed molecules.
The comprehension of the structure and growth of the first wetting layers on certain surfaces is crucial to understand and control technological processes such as corrosion and electrochemical processes on metallic substrates. Focussing on ionic and graphitic surfaces, we will explore the nature of atmospheric chemical processes, such as catalytic reactions occurring on tropospheric aerosols.
One of the goals on this project is to understand how weak interactions (dipolar, van der Waals, etc) may affect to the self-assembly of small molecules of biological interest.
Electron transport in tunneling and contact regime
Contact person: Dr. Aran Garcia-Lekue ([log in to unmask]).
UPV/EHU supervisor: Prof. Andrés Arnau
In recent years, electron transport through nanostructures has attracted great interest as nanoscale junctions or molecular devices may create a molecular electronics technology in the future. The current flowing through a nanostructure can be measured using scanning tunneling microscopy (STM) and break junction techniques. The aim of this project is to simulate electron transport in nanostructures, e.g. single molecules sandwiched between metallic electrodes, aimed at the prediction and/or understanding of experimental observations.
