Keterangan :
Delft University of Technology is a multifaceted institution offering education and carrying out research within the technical sciences at an internationally recognized level. Education, research and designs are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft we work in an environment where technical sciences and society converge. TU Delft comprises 8 faculties, unique laboratories, research institutes and schools.
Faculty of Applied Sciences
This is a large, research-oriented faculty providing excellent, challenging education and conducting pioneering, cutting-edge fundamental research of great societal relevance in the natural sciences.
It provides a world-class training ground for future leaders in scientific professional practice and research. With more than 60 different nationalities studying and working together, it provides a rich and culturally diverse environment.
The Radiation, Radionuclides & Reactors department
The department of Radiation, Radionuclides & Reactors (www.rrr.tudelft.nl) is accommodated in the Reactor Institute Delft (RID). Binding elements are nuclear radiation and reactions. Although its areas of interest are varied, whether they be materials, sensors and instrumentation, energy and sustainable production or health, all research is related to radiation in some way. In experimental research, extensive use is made of the research facilities of the Reactor Institute Delft as well as of large international research facilities.
The section Radiation Detection & Matter (RD&M) conducts intensive research on the physics of light emitting inorganic semiconducting or insulating materials. Our main expertise concerns the light emission of lanthanide impurities. Through many years of applied and fundamental research on scintillators, lamp and display phosphors, afterglow and storage phosphors, general models have been developed in our section that explain and predict observed phenomena. This resulted in the invention of exciting new scintillators like LaBr3:Ce3+ that are now commercially available and applied for radiation detection instruments for space explorations and medical diagnostics. Our models also allow for the design of new lanthanide-based photonic materials. Novel lanthanide-based switchable materials are a promising example of this.
The section Radiation Detection & Matter has a PhD student vacancy in the field of switchable materials.
Project and job description
Materials that switch from a semiconductor (transparent) to a metal (reflective) by a single pulse of laser light can be used as building blocks for fast optical switches. Such all-optical switches, in which light pulses are controlled by other light pulses, are needed to avoid slow electrical switching in optical data communication networks and may be applied in future optical computers. Several binary lanthanide materials display a heat or pressure induced reversible semiconductor-to-metal (SM) phase transition with spectacular reflectivity changes at the regular telecommunication wavelength. So far, the dynamical aspects of this switching process have not yet been addressed.
The PhD candidate will study this unique reversible SM phase transition in a new class of switchable lanthanide materials. She or he will use optical techniques to characterize the materials and trigger the phase transition by applying pressure, changing temperature or varying material composition. In addition, the PhD candidate will study the dynamics of the phase transition by triggering it with ultrashort pulses of laser light. The goal is to gain a fundamental understanding of this photo-induced phase transition and to study its potential for fast photo switches.
The project will be carried out in collaboration with several national and international university groups in Bern, Gent, Eindhoven and Paris specializing in material synthesis. Besides the experimental facilities of the RDM section, the PhD student will have the opportunity to perform measurements at other Dutch university groups in Eindhoven, Delft, and Groningen.
Requirements
Applicants should preferably be experimental physicists with a background in solid-state physics and/or photonics. Experience with lasers or laser-induced processes is an advantage.
Delft University of Technology is a bilingual organization; a good command of English (written and oral) is essential.
Conditions of employment
This position is based on an employment contract of four years (48 months) and is for a maximum of 38 hours per week (1 FTE). The estimated monthly salary is based on scale 10 with a maximum of € 2,502 gross per month based on a full-time appointment. Secondary benefits and other employment conditions are in accordance with the Collective Labour Agreement for Dutch Universities.
The successful candidate will be employed by Delft University of Technology for a period of four years during which time he/she is expected to write a dissertation leading to the PhD title.
Information and application
For further details on the position you are welcome to contact Dr Erik van der Kolk, telephone: +31(0)15 -27 83464; e-mail: e.vanderkolk@tudelft.nl or Dr P. Dorenbos, telephone: +31(0)15 -27 81336; email: p.dorenbos@tudelft.nl.
To apply, please send your application letter together with a curriculum vitae as soon as possible, but in any case before October 15, 2007 to: Delft University of Technology, for the attention of Dr E. van der Kolk, Mekelweg 15, 2629 JB Delft, the Netherlands; or apply online: e.vanderkolk@tudelft.nl. Foreign students are advised to mention their GRE (physics) and TOEFL scores in the application letter.
When applying for this position please mention the vacancy number: TNWRRR07-043.
