The area of Electronics and Photonics covers research in materials, integration technologies and circuits, as well as design methodologies for electronic and photonic devices and systems. Its aim is to push forward the state of the art in current technologies and bring greater understanding to the possibilities for new materials as well as novel device and system concepts.

Computational nanoelectronics Nanoelectronics on the computer test bench Electronic components are only a few nanometres (billionth of a metre) in size. The tinier their dimensions become, however, the harder they are to manufacture: quantum mechanical effects such as the tunnelling of electrons through potential barriers start to manifest themselves at the nanometre scale and affect the characteristics of nanoelectronic devices.

D-ITET is a first-class educational institution where teaching is strongly linked to research. Our graduates do cutting-edge research and take leadership positions in the areas of electrical engineering and information technology in Switzerland and worldwide.

D-ITET offers a comprehensive education programme Specialisations that covers a great many thematic areas in electronics, Our main Bachelor's /Master's programme permits photonics, information and communication, energy, specialisation in one of the following areas: and biomedical engineering. – Communications – Computers and networks The Bachelor's programme – Electronics and photonics The Bachelor's degree in the Department of Information – Energy and power electronics Technology and Electrical Engineering takes six semes- – Systems and control ters to complete, in which the necessary foundations – Biomedical engineering in mathematics, physics and computer science as well as the theoretical and methodical foundations of elec- Interdisciplinary Master's programmes trical engineering/electronics are taught. The timetable We also offer the following interdisciplinary Master's is clearly defined in the first four semesters, but from programmes in cooperation with other departments the fifth semester on there is plenty of room for students of ETH Zurich: to choose whether to focus more on engineering or – Biomedical Engineering humanities, and on theory or practice. – Energy Science and Technology – Robotics, Systems and Control The Master's programme – Micro- and Nanosystems The Master's programme at D-ITET serves to deepen – Neural Systems and Computation students' specialisations and leads to a qualifying degree. – Data Science In addition to specific courses, research is an essential – Management, Technology and Economics part of the Master's degree. The students will find an in- ternational, stimulating environment at D-ITET that lays German and English the ideal foundations for their future work environment While Bachelor's courses are mainly taught in German, or for a doctorate. Bachelor's graduates can either enter all courses at Master's level are taught in English. In the consecutive Master's programme directly or apply for the Master's programmes, every student is supported one of the many interdisciplinary Master's programmes. by a professor (“tutor”), who assists the student in the selection of courses. The Master's programmes are also the preferred path towards our doctoral programmes for students who have obtained Bachelor's degrees from outside ETH Zurich.

“I'm studying electrical engineering because I have seen the many great achievements and inventions of electrical engineers over recent years. I think that this will continue into the future and I would like to be a part of it.” Felix B., Master's student at D-ITET
