Abstract

Ferroelectricity has been discovered about a century ago. As an electric cousin of the widely known ferromagnetism, ferroelectric materials have in no way shown fewer applications, from memories to sensors, actuators and transducers, and from military use cases to industrial and medical sectors. Because of its structural and functional flexibility and complexity, strong ferroelectrics usually result in excellent piezoelectric materials. Piezoelectrics are able to realize electromechanical coupling in the materials and thus can convert kinetic energy into electricity and vice versa. This course will give an overview of the fundamentals as well as the frontier research of ferroelectric and piezoelectric materials and devices, which is an essential topic in the field of microelectronics.

Qualifications

Participants should have acquired university-level knowledge of mathematics, physics, chemistry, and electronics.

Teaching language

English

Subject

ITEE-DP Electrical Engineering

Students from other natural science, engineering and bioscience doctoral programmes will also find benefits from attending the course.

Content

Five lectures and three seminars. The lectures will be delivered by guest lecturer Prof. Jürgen Rödel (TU Darmstadt, Germany) and the responsible teacher Assist. Prof. Yang Bai (Microelectronics, ITEE, University of Oulu). The seminars are discussion-based and will require active interaction among the participants and the facilitator (Yang Bai). Topics of each lecture and seminar can be found in the course schedule.

Assessment methods and criteria

To qualify for the 2 ECTS offered by the course, two assessment criteria must be satisfied:

(1) Students are required to attend all lectures and seminars either in person or via live Zoom meeting. Compensation to absence is allowed by watching the recorded videos and then submitting a free-form reflection paper for each absent lecture or seminar.

(2) The students must also complete a final assessment. Two options are available: (a) Submit a reflection paper discussing the learnt knowledge as well as correlation to own research; (b) Give a 20-minute presentation of research story telling during Seminar 2 or 3.

Detailed instructions of assessments will be given in Seminar 1.

Form of instruction

The course is taught in hybrid mode. The students can either attend in person or virtually. The total study length should be 54 hours (equivalent to 2 ECTS) including 10 hours for attending lectures, 6 hours for attending seminars and 38 hours for self-study and assessments.
