About This PhD Project

Project Description

Electric field effects can be used to induce changes of the magnetic properties and resulting magnetoresistance effects. This can result in novel approaches where information is not encoded in discrete values and processed in Boolean logic gates but novel neuromorphic computing schemes can be employed.

In this project, we will develop and deposit high quality material stacks for experiments of electric field manipulation. In particular using high-k dielectrics and ionic conductors can be used to continuously tune the magnetic properties such as anisotropies, the strength of the exchange interactions leading to a control of the spin structures including the Curie temperature, etc.

High-k dielectric material deposition by sputtering is an established process in the semiconductor industry. We will apply this to the new material systems investigated among the partners and provide them with the layers of their needs using some of the world’s most advanced sputter tools. In addition, new materials only tested now for some small scale devices by the partners as e.g. Gd2O3, which is an ionic conductor will be tested for their scalability, i.e. deposition on large 200 mm or 300 mm wafers.

We will gauge the applicability of these continuous tenability of properties for devices, such as synaptic transistors and related device concepts. In particular we will study the scalability of these approaches and evaluate the use in industrial fabrication environments.

We will employ in particular advanced sputter deposition using state-of-the-art deposition tools such as the Singulus Rotaris system as well as structural and magnetic characterization techniques that combined provide a broad scientific and technological training.

General requirements:

• Be fluent in English
• Have not been a resident or have conducted your main activity (studies, work, etc.) for more than 12 months within the last three years in the PhD position’s host country.
• Be in the first four years of your research career. This is measured from the date you obtained a degree that allows you to enroll in a PhD program.
• Have not yet been awarded a doctoral degree

Specific requirements/skills:

-Essential:

• Master degree or equivalent in condensed matter physics, applied physics, nanosciences, materials sciences, nanoelectronics or similar.
• Excellent oral and written communication skills, well developed interpersonal communication.
• Enthusiastic, self-motivated, willing to learn and work in an environment with strong teamwork.

-Desirable:

• Experience in vacuum technologies and thin film deposition
• Experience in materials characterization

This PhD position will be carried out in the framework of the EU’s Marie Sklodowska Curie Innovative Training Network MagnEFi which includes 11 partners, both academic (8) and industrial (3), located in France, Germany, Italy, Finland, Spain, England and the Netherlands. We will work together to develop a unique integrative approach to electric-field control of magnetism. Innovative electric-field control schemes based on Strain (S), Gating (G) and Light (L) will be thoroughly investigated and combined to produce a new class of enhanced multifunctional spintronics devices with S+G, S+L and G+L capabilities.

The benefits of this project for you and the future of your career are many fold, here's a few key aspects that MagnEFi can offer you:

• Working on the forefront of one of the most promising topics in spintronics in an international team lead by world recognised EU experts in the field.
• Benefiting from the extensive training program which includes basic and modern aspects of spintronics as well as of other exiting emerging fields such as artificial intelligence but also includes entrepreneurship, scientific writing, communication skills and intellectual property.
• Visiting other partners of the network to learn about their specific techniques and to establish collaborations which will interconnect experimenters and theorists, basic scientists and engineers, and academia and industry.
• Being granted a prestigious EU fellowship with a very competitive salary including mobility and family allowance.
• Establishing a professional network with leading scientists in academia and industry.
• Being prepared for the future after your PhD, training also includes courses on writing competitive job applications for academia and industry, writing high-impact research proposals as well as on preparing job interviews.
