昆士兰大学招博士两名，具体细节如下，符合条件者踊跃报名，极力推荐！ Call for PhD Research Positions (x2) Regulating Phase Transitions and Formation Energetics inMetal Halide Perovskite-Based Optoelectronics School of Mathematics and Physics, The University of Queensland, Brisbane, QLD, 4072, Australia Research outline: Solution-processed all-inorganic CsPbI3 perovskite semiconductors are increasingly being considered for applications well beyond photovoltaics, for example, as the active regions within thin film photonic devices like cameras and LEDs. The optoelectronic perovskite phase is, however, unstable at room temperature, with a relatively large research community (spanning several sub-disciples) looking for new and effective ways to engineer a stable CsPbI3 perovskite structure. Changing the phase energetics ultimately means moving away from an normal equilibrium crystal, whereby disorder in its different forms, i.e., strain, (stereo)chemical, defects and interfaces, etc., can be used to regulate phase formation energies and prototype functional photonic devices. Job description: This project aims to develop deep structure-property relationships and materials engineering protocols to generate stable forms of the emerging inorganic halide perovskite semiconductors. The project expects to arrive at working light emitter and detector prototypes via a three-dimensional, multi-length scale strain engineering approach that utilises materials processing techniques already used in the semiconductor industry. The expected outcomes include the development of new stabilisation methods which will directly impact the success of future perovskite optoelectronic devices and technologies. All aspects of the work plan (materials synthesis and characterization, as well as device fabrication and testing) will be completed in a supportive environment designed to help the applicant learn and grow their research skills in a multidisciplinary environment. Candidates must be eligible for a PhD course in solid-state physics. Research experience in one (or more) of the following areas is desirable: - Crystallographic characterisation (X-ray or neutron scattering, quantitative structural refinement) - Ab initio materials modelling techniques, including MD and DFT. - Phase change materials - Synchrotron science - Routine characterization of optoelectronic/semiconductor materials; XRD, SEM, AFM, PL… - Clean room experience (highly desirable) - Photonic device fabrication and testing; i.e., LEDs, lasers, photodetectors… (highly desirable) - Solution processing of lead halide perovskite semiconductors - Excellent written and oral communication skills in English Interested? Please send your CV and a one page motivation letter to (deadline March 20th 2023) Dr. Julian Steele +61 456 020 850 / julianandrew.steele@uq.edu.au [Application submission platform] |
