The group 'Experimental Physics of Complex Systems (EpkoS)' of the Energy and Semiconductor Research Laboratory (EHF) at the Physics Institute of the University of Oldenburg offers at the earliest possible date

one PhD student position (m/f/d)
(research assistant, salary TV-L E13, at least 50 %)
EU-project 'Heat transport in nonlinear energy filter systems'

for the period of 3 years. It is intended to qualify for a PhD during this time.

The energy and heat management at the nanoscale plays an essential role in the further miniaturization of electronic devices. We contribute our competence to an international research consortium by means of an in house developed scanning thermal microscope (SThM) [1]. It is based on a scanning tunneling microscope (STM) and is worldwide unique because a resolution of a few nanometers is achieved and the surface texture can be imaged at the same time [2].

At this position you are working in a cooperative project of the EU. Our aim is the investigation of the electronic and phononic conduction of single molecules and the near field heat and energy transfer at the nanoscale [3]. The international highly-ranked cooperation for the first time facilitates gaining fundamental insights on smallest length scales and incorporating these into technical applications.

In the team, you will investigate the electrical and thermal characteristics of molecular films fabricated by yourself and of the cooperation partners micromachined devices with a high spatial resolution. With the knowledge gained we will optimize the synthesized molecules and the devices.

Aims and topics:

  • Measurements of the heat transfer at different surfaces with a worldwide unique scanning probe microscope
  • Characterization of molecular films and micromachined devices
  • International Collaboration with our partners in the European Community (England, Finland, France, and Swiss)

Required qualification:

  • University master's (or diploma) degree above average in experimental physics or a closely related subject
  • Profound knowledge of surface science
  • Very good English skills, German skills are helpful

Beneficial prior knowledge or experience in scanning probe microscopy, low temperature physics, vacuum technology, and programming skills are welcome. Inputs to the supervision of students and teaching in tutorials and lab courses are expected.

We offer professional working environment on a high scientific level and well-equipped laboratories. You will gain competences in the fields of scanning probe microscopy, surface science, low temperature physics, and ultra-high vacuum technology. You will attend at international workshops and conferences. At the University of Oldenburg, we have different possibilities to widen your view by participating at graduate schools.

The University of Oldenburg is dedicated to increase the percentage of female employees in the field of science. Therefore, female candidates are strongly encouraged to apply. According to § 21, 3 NHG female applicants are to be preferentially considered in case of equal qualification. Applicants with disabilities will be given preference in case of equal qualification.

We are looking forward to your job application. Please send your application including the usual documents (cover letter, CV, graduation results, job references etc.; referring to code: EFINED) - preferably by e-mail as a single pdf-file - by August 11th, 2019 to kitt/tgelq4rc@unta8i-fwoldenburg.dem8i and janengut.nee9jbwrksmlhenjcnpp@uniuyj-olt/tiidenbxyurg.de
