The Faculty of Physical Sciences seeks applicants to fill a PhD student position for 3 years, for the project: Reactive high power impulse magnetron sputtering (R-HiPIMS).
The high power impulse magnetron sputtering (HiPIMS) discharge is an ionized physical vapor deposition (IPVD) technique that has attracted much interest lately. In HiPIMS, high power is applied to the magnetron target in unipolar pulses at low duty cycle and low repetition frequency while keeping the average power about two orders of magnitude lower than the peak power. This results in a high plasma density (electron density) and high ionization fraction of the sputtered vapor. This high ionization fraction allows for better control of the film growth as it allows for controlling the energy and direction of the deposition species, which is a significant advantage over conventional dc magnetron sputtering (dcMS) where the sputtered vapor consists mainly of neutral species. In reactive sputtering where a molecular gas is added to the inert working gas, in order to grow oxides, nitrides or carbides, this high electron density is expected to give high dissociation fraction of the molecular gas. Further information on the project can be found at http://langmuir.raunvis.hi.is/~tumi/hipims.html
During this PhD project the student will develop a detailed understanding of physical vapor deposition of thin films. The PhD student will grow thin films by reactive magnetron sputtering applying dc magnetron sputtering, asymmetric bipolar pulsed magnetron sputtering and HiPIMS. The PhD student will characterize the film properties, with methods such as X-ray reflectometry, X-ray Diffraction, electrical measurements and ellipsometry. The PhD student will explore the discharge parameters and plasma properties and develop models of the plasma behavior. As part of the project, the PhD student will be expected to communicate research results both orally at international conferences and in writing in scientific journals.
Applicants should have an MSc degree in physics, engineering physics, electrical engineering, materials science, or chemical engineering. Experience in materials characterization and thin film growth is desired. The applicant needs to be able to work independently and have strong communication and interpersonal skills.
Application deadline is July 31st 2015. The PhD. student position is for 3 years and starts September 1st 2015. The selected candidate will need to send a formal application for a PhD. studentship at the University of Iceland in due time.
For further information please contact Professor Jón Tómas Guðmundsson, firstname.lastname@example.org or +354-525-4946+354-525-4946.
The application shall include a description of the applicant's interests in the project and how they can contribute to the project. The application should be no longer than three pages. The application and, i) CV, ii) certificates of education (BS and MSc degree), iii) two reference letters with contact information, should be sent to: email@example.com marked HI15060013 Applications that are not sent electronically should be sent in duplicate to Human Resource Division, University of Iceland, Main Building, Sæmundargötu 2, 101 Reykjavík. All applications will be answered and applicants will be informed about the appointment when a decision has been made.
Salary for the position is according to funding from the University of Iceland Research Fund.
Appointments to positions at the University of Iceland are made in consideration of the Equal Rights Policy of the University of Iceland.
At the School of Engineering and Natural Sciences about 300 people are employed in research and teaching. The School offers an international environment, with the number of international employees and students increasing each year. Currently about a quarter of all employees and graduate students are international. There are around 2900 students at the School, divided into six Faculties, including approximately 340 Master’s students and 150 doctoral students. The research institutes at the School are the Engineering Research Institute, the Institute of Life and Environmental Sciences, the Science Institute (subdivided into the Institute of Earth Sciences and Institute of Physical Sciences), and the Institute for Sustainability Studies, which is an interdisciplinary institute under the auspices of all five Schools of the University of Iceland.
The University of Iceland is the largest teaching, research and science institute in Iceland and is ranked among the top 300 universities in the world by Times Higher Education.
