We are now hiring

Two Doctoral Students and One Postdoctoral Researcher to work for the project ‘‘Low-energy high-performance sensing materials for environment digitalization’’.

The faculty and the research group

The project focuses on research of piezoceramics with ultralow fabrication temperatures, paving a way towards energy saving in materials fabrication, enhancement for integration capability and sustainable development. Piezoceramics are widely used in sensors, which constitute vital components in modern technologies requiring conversion between mechanical and electrical energies. Piezoceramics need to be manufactured at over 1000 degrees Celsius, consuming a considerable amount of energy and leading to increased emission. This project aims to overturn 100 years’ history by making piezoceramics at temperatures lower than 350 degrees Celsius, via methodologies of surface chemistry and ceramic-ceramic composite. Success of this project will not only help to save over 90 % of energy used by high temperature sintering in piezoceramics industry, but also stimulate the advancement of novel multi‑functional components and electronic integration in smart devices and systems.

The positions are placed at the Microelectronics Research Unit (MIC, http://www.oulu.fi/microelectronics/), Faculty of Information Technology and Electrical Engineering (ITEE, http://www.oulu.fi/itee). Microelectronics Research Unit is an internationally recognized, high excellence and quality unit with significant scientific impact in the fields of micro and nanosystem technologies. The education and research fields are materials, devices and their implementation technologies with special emphasis on electronics, photonics and telecommunication applications. The research is carried out in several multidisciplinary research groups in close co-operation with top research groups in Europe, Asia and USA and global and domestic industrial partners. Research projects are funded by the Academy of Finland, EU, and Business Finland among others. Scientific research of the Microelectronics Research Unit was evaluated in 2013 in the international research assessment of the University of Oulu to the level 6 (max. 6). The research unit is a dynamic and inspiring high-level research environment with up-to-date facilities and equipment.

Open positions for two doctoral students

  • The doctoral students will work to fabricate chemically surface activated piezoelectric particles and ceramics.
  • The doctoral students will also work to fabricate and test piezoelectric actuators, sensors and/or energy harvesters made by the developed ceramics.
  • The doctoral students will be supervised to work on the experiments and research results dissemination (e.g., publications, conference presentations), as well as writing and defending the D.Sc. thesis.

Qualification requirements for a doctoral student

  • We expect a master´s degree in chemistry, materials science or a related subject.
  • You have relevant research/work experience in surface chemistry, piezoelectric materials, or perovskite-structured compounds.
