PhD Position - Quality-enhanced power semiconductor devices for reliable energy conversion (QEPSREC) (RESPONSE DP, ESR 10)

100%, Zurich, fixed-term

Within the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 847585, ETH Zurich is offering a 36-month PhD position for an early-stage researchers (ESR) in in the area of sustainable energy systems.

Job description

We are looking for a motivated PhD candidate working on the rapidly growing field of wide-bandgap semiconductors for power electronic applications. Aim of this project is the development of a novel implantation technology to realize more efficient silicon carbide (SiC) based super junction devices. Main tasks include the modelling of adequate device structures, the fabrication of SiC devices as well as their electrical characterization in terms of performance and reliability.

A planned secondment of two times three months at mi2-factory GmbH in Jena, Germany, is part of this project. During this secondment, the ESR will be trained in performing, evaluating and simulating ion irradiation experiments on 4H-SiC.  The doping of a semiconductor base material by ion implantation is a commonly employed technique, however, super junction devices require highly uniform doping profiles with very large aspect ratios. Hence, main focus during the secondment will be the development of a novel ion implantation process to deliver the stringent requirements for these energy-efficient deep junction devices.

Your profile

To perform successfully, potential candidates should have a background in Physics, Material Science, Electrical Engineering or a related field with a solid background in semiconductor physics. Experience in a cleanroom environment and with electrical characterization techniques are advantageous.

We are looking for highly motivated, creative, and committed candidates with excellent writing and communication skills, both oral and written. The ability to combine strong individual research with teamwork within the project completes your profile. The output of the research will be published in relevant scientific journals of the field and application-relevant findings will be disseminated to a broader technical community.

Eligibility: Early stage researcher in the first 4 years (full-time equivalent) of their research careers, including the period of research training, starting at the date of obtaining the degree which would formally entitle them to embark on a doctorate either in the country in which the degree was obtained or in the country in which the initial training activities are provided.

At the time of recruitment (for call 2 = July 1, 2020) by the host organisation, researchers must not have resided or carried out their main activity (work, studies, etc.) in Switzerland for more than 12 months in the 3 years immediately before the reference date. Compulsory national service and/or short stays such as holidays are not taken into account.

Language requirement: Proficient oral and written English skills are expected.

Main Research Field: Semiconductor physics.

Sub Research Field: Wide-bandgap electronics.

RESPONSE is open to applicants of any nationality.

For submitting your online application: (select PhD Program Science and Policy). The online application should contain all information as indicated by the application portal. Moreover, the following documents have to be uploaded under “further documents”: 1) a letter of motivation to join a) the RESPONSE doctoral programme and b) to apply for this specific positon (ESR xx), 2) a comprehensive tabular CV, and 3) transcripts of records. If you apply for more than one RESPONSE position, please refer to them in your letter of motivation. Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.


We are offering an interesting position at the interface of science and policy. While working in an international, interdisciplinary and innovative research environment at ETH Zurich, the ESR will be jointly co-supervised by the Advanced Power Semiconductor Laboratory at ETH Zurich and its industrial partner mi2-factory GmbH in Jena, Germany. 

The complete 36 months will be under 100% working contracts.

The PhD salary follows the regulations of ETH Zurich and will be according to EU regulations for Marie Skłodowska-Curie Early Stage Researchers. The monthly gross salary will not be lower than CHF 3’920.

The successful candidate will be matriculated and will have a working contract at ETH Zurich. He/she will work in Switzerland. The secondment will take place in Jena, Germany.

Expected starting date of the working contract: 01.09.2020.
