PhD scholarship in materials science

PhD stipend of ~$30000 AUD pa for 3 years (tax free).
Tuition fees are waived.

A fully-funded PhD scholarship is available in materials science to study organic light emitting diodes (OLEDs). An OLED uses organic semiconductor materials to generate light, for example, in mobile phone screens and TVs. OLED displays are already in the market, but there is still significant room for improvement. A major gap in understanding is the impact of nano- and microscale film structure on device performance. There is an opportunity for a motivated PhD student to address these challenges and contribute to the next generation of organic semiconductor technology.

The broader context
This PhD project is part of a multi-university (University of Queensland, Murdoch University and James Cook University) and multi-disciplinary collaboration funded by the Australian Research Council (ARC) Discovery Projects. There are a total of three PhD positions available. This project focuses on electrical properties of materials and devices. The other two projects are: (1) experimental studies of thin film morphology at the University of Queensland under the primary supervision of Prof. Ian Gentle, and (2) computational studies at James Cook University under the primary supervision of Dr. Bronson Philippa. All three PhD students will work closely together as a cohort, in collaboration with the academics and postdoctoral researchers at each institution.

About the PhD project
The successful applicant will study the electrical currents, charge transport and photocarrier recombination in novel nano-structured semiconductors and optoelectronic devices. Standard Time-of-Flight, quasi steady state current-voltage, Hall-effect as well as novel CELIV methods will be used. Time-dependent electrical characterisation of organic semiconductors and OLED devices using oscilloscopes, signal generators, voltage-current supply and measure units, lasers, LEDs with pulsed electronics will be applied. C and Labview language programming of measurement equipment will be required.

What we offer
The successful applicant will receive an ARC-funded stipend equal in value to the Research Training Program Scholarship. The stipend is for three years with a possible extension of 6 months in approved circumstances. We also provide funding to support the research, including for travel to visit collaborators and attend conferences.

Eligibility requirements
Applicants must meet Murdoch’s entry requirements for admission to a PhD. Award of the scholarship is conditional on the university accepting your enrolment. The successful applicant will be guided through the process of formally applying for admission.
This is an interdisciplinary project so applicants from a wide range of academic backgrounds will be considered. Applications should have strong undergraduate knowledge in some of these areas:
• Semiconductor physics, electrochemistry and materials science.
• Computer programming.
This project is based in Murdoch, Western Australia and is available for immediate start. For eligibility reasons the candidate must be living in Australia.

How to apply
To express your interest in this scholarship and PhD research opportunity, please prepare the following items:
1. A cover letter describing the exciting projects you have worked on in the past.
2. A brief CV, including qualifications, academic achievements, list of publications, work history, and references.
3. A copy of your academic transcript(s).
Please submit your application via email to

The scholarship may be filled before the end of the life of the advertising period, so you are encouraged to get in contact as soon as possible.

My CV, brief 

Almantas Pivrikas has graduated a Bachelor degree at the faculty of physics at Vilnius University in Lithuania. He continued the studies at the Solid State Electronics and Condensed Matter Physics department headed by Prof. Gytis Juska where he obtained Master’s degree. Here he actively participated in development and application of novel Charge Extraction by Linearly Increasing Voltage (CELIV) technique used to study the transport of negative and positive charges in inorganic and organic semiconductors.
For PhD studies he joined the group of Prof. Ronald Osterbacka at Abo Akademi University in Finland where he continued the research of charge transport in various organic materials and devices. Here he discovered unexpected phenomena of reduced (non-Langevin recombination) photocarrier recombination in disordered organic materials.
After receiving a PhD degree, Almantas accepted a fix-term assistant professor contract in the group of Prof. Niyazi Serdar Sariciftci, in Physical Chemistry Department and Linz Institute for Organic Solar Cells (LIOS) at Johannes Kepler University Linz, Austria. Here he further developed powerful transient techniques for charge transport studies and extended his expertise in other optoelectronic devices such as organic field effect transistors and light emitting diodes.
To continue his carrier in academic research, he joined the group headed by Prof. Paul Burn and Prof. Paul Meredith at the School of Chemistry Molecular Biosciences, The University of Queensland, Brisbane, Australia. In 2012 he was awarded ARC DECRA fellowship.
Since the beginning of 2015 Almantas continues his research and teaching at Murdoch University, Perth, Western Australia.
