Functional molecules are foreseen as a potential replacement to diodes, transistors, or switches within a hybrid metal-organic circuit, provided that well-controlled metal-molecule contacts are established. These contacts impact the quality of the electronic devices and represent therefore one of the most urgent matters to address in molecular electronics. Our approach consists in using a Scanning Tunneling Microscope (STM) in both tunneling and contact regimes to accurately map the transport properties of a single molecule on a metal surface (Fig. 1) [1, 2]. The measurements are carried out at low temperature and in ultrahigh vacuum to ensure a clean and reproducible experimental environment.
The orignal aspect of the present research project is to exploit a spin-polarized STM (SP-STM) to study the spin injection into nanoscale structures like single atoms and molecules. The ability to manipulate the electron spin in organic molecular materials offers in fact a new route towards spin electronics, both from fundamental and technological points of view. Recently, we were able to image by SP-STM the stationary spin states of a single molecule with an unprecedented spatial and energetic resolution [3]. At baseline, the research project will be devoted at engineering magnetic junctions with the tip of the STM and characterizing the magneto-transport with a vector magnetic field. Stable junctions can indeed be obtained with STM by bringing the tip into contact with a well-characterized atom or molecule [1,4]. Atom manipulation will also be employed to modify the magneto-resistance of existing structures.

The Ph.D. candidate will be expected to carry out together with other members of the group an ambitious research program related to the present topic. Two low-temperature STMs are currently available in the group. Theoretical support will be available from the international collaborations we have built over the past years. The position will run for three years with a salary in the ballpark of 1650 Euro per month (health care included). No teaching is required.

We are looking for highly motivated candidates with a Scientific Master degree. They should have a background in physics or physical chemistry, and a good knowledge in material science. Taste and skills for experimental work are desirable. Candidates are invited to send a curriculum vitae, possibly accompanied by supporting letters to: bucher@ipcms.u-strasbg.fr
Deadline for application : 7th of june 2010.
