Dr Antonio Feteira joined Sheffield Hallam University in 2012 as a Senior Lecturer and Director of the Multiferroics Christian Doppler Lab.
He graduated with a BSc in Materials Engineering from the University of Aveiro (Portugal) in 1998. Antonio went on to specialise advanced ceramics and was awarded a MSc in Ceramics Science and Engineering from the University of Sheffield (UK) in 1999.
In 1999, he started working towards his PhD at the University of Sheffield (UK) within Profs. Reaney and Sinclair’s groups and in collaboration with Morgan Electroceramics. During his PhD studies he was awarded a Worldwide Universities Network Scholarship to the Penn State University (USA) and a Marie Curie Training Fellowship in Advanced Microscopy at the Max Planck Institut für Metallforschung (Germany).
Upon the conclusion of his PhD in 2004, he became a Postdoctoral research associate at the University of Sheffield (UK), working in advanced functional oxides within Prof. Sinclair’s group. Between 2004 and 2007 he hold visiting research positions at Penn State University (USA), within Prof. Lanagan's group and Complutense University of Madrid (Spain), with Prof. Calbet's group.
In 2008, Antonio moved to Austria to work within the R&D research group of TDK EPC. Simultaneously, he acted as Visiting Lecturer at the University of Sheffield. One and half years later, he joined the School of Chemistry as a Birmingham Science City fellow and also became an Associate Fellow in the Department of Physics at Warwick University.
Currently, he also holds a Visiting Advanced Fellow position at the University of Sheffield.
He has published over 45 research papers in the field of advanced functional oxides for electronics and acts as an associate editor for the Journal of the American Ceramic Society. He received research grants from the Royal Society and the Christian Doppler Society. He is a member of the Cost Action SIMUFER (Single- and multiphase ferroics and multiferroics with restricted geometries).
Research Interests
Lead free piezoelectrics
Piezoelectrics are used in a multitude of applications ranging from micropositioning systems, fuel-injection actuators and printing heads The most successful piezoceramics are based on PbTiO3 and PbZrO3. Nevertheless, recent environmental legislation triggered the search for lead-free piezoelectrics. We have been investigating K1/2Na1/2NbO3 and Bi1/2Na1/2TiO3-based piezoelectric ceramics in collaboration with Prof. Reichmann from the Graz University of Technology in Austria.
Low temperature firing oxides for electronics
3D integration of modern electronic passive components requires materials with firing temperatures lower than 960°C. Currently, we are investigating Tellurium-based oxides in collaboration with Dr. Tim Jackson from the School of Electrical Engineering at the University of Birmingham.
Multiferroics
Multiferroics are materials that show simultaneous ferromagnetic and ferroelectric ordering. Research into multiferroics has been triggered by the potential use of these materials in emerging technologies, such as in memories and tunable microwave applications. In collaboration with TDK EPC (Austria) we have been investigating novel routes to multiferroics.
