Phd Position

**Your Job**:
The aim of this project is to fabricate individual 1T1R-elements and small 1T1R-crossbar arrays in one or two layers in the BEOL area of silicon chips and to characterize them electrically. This position aims on design and fabrication of metal-oxide-based memristive devices with the focus on the co-integration with transistors made of 2D-materials. Materials compatibility should be analysed using the nano-analytical methods provided by the partners in TRR 404. Your tasks in detail are:

- Design, fabrication, optimisation and physical analysis of nano-structured memristive devices based on transition metal oxides using process technologies that are compatible with BEOL and transistors made of 2D semiconductors
- Design of process flows and device layouts that enable the area-efficient co-integration of 1T1R elements made of 2D transistors and metal oxide memristive devices and offer scaling potential
- Co-integration of the memristive devices with the 2D-FETs including layout tasks and process modifications reaching a high yield and a good device uniformity
- Electrical characterisation of the 1T1R elements and small crossbar arrays in relation to defined use cases including the development of Python codes
- Exchange and discussion of results within the consortium, taking into account integration issues and electrical performance
- Publication of the results in peer-reviewed scientific journals and presentation at project meetings and conferences

**Your Profile**:

- Excellent Masters degree in Physics, Material Science or Electrical Engineering with focus on semiconductor technology or nanotechnology
- Willingness and ability to think beyond the boundaries of your field, to act team-oriented in an international and diverse environment and to live an open and constructive communication
- Strong analytic and problem-solving skills, creativity, and an independent, target
- and solution-driven work attitude
- Profound knowledge on solid state physics and semiconductor physics
- Experience and strong interest in experimental and laboratory (clean room) work
- Experience with programming in Python or Matlab
Fluent speaking and writing skills in English and knowledge of German
To apply, please submit a complete CV, letter of motivation and university degree records (both Bachelor's and Master's degree).
