PhD Scholarship in Quantum Nanofabrication

Are you eager to advance your scientific career at the cutting-edge of quantum materials and nanotechnology? 

DTU Physics and DTU NanoLab offer a fully funded PhD position (3 years) to develop groundbreaking electron-beam lithography (EBL) methods that will redefine what is achievable in quantum device fabrication. You will push lithography resolution limits down to the quantum regime, demonstrating the fabrication of robust artificial quantum superlattices that have never before been realized.

Joining our dynamic, international research community, you will gain unique, high-demand competencies in quantum-focused nanofabrication, advanced materials science, and quantum electronics. With access to DTU Nanolab's state-of-the-art cleanroom facilities, you will establish yourself at the forefront of quantum technology, positioning your career for long-term success and global scientific impact.   

Your primary role will be to pioneer and optimize advanced electron-beam lithography techniques to demonstrate reliable fabrication of quantum superlattices at unprecedented spatial resolutions (below 15 nm). You will leverage DTU Nanolab’s best-in-class 100 kV EBL system, applying these techniques directly to well-established two-dimensional (2D) materials such as graphene, α-RuCl₃, and transition metal dichalcogenides (TMDs).

This PhD project is highly focused on methodology, resolution enhancement, and reproducibility. It will serve as a foundation, enabling future studies on novel quantum phenomena in these newly accessible quantum superlattices. Specific research activities will include: 

• Developing and optimizing ultra-high-resolution lithographic processes:
  You will explore and refine unconventional electron-beam resists (e.g., HSQ, metal fluorides, alkali halides) to reliably achieve robust pitches below 15 nm.
• Nanoscale characterization: You will validate your lithographic patterns using advanced microscopy methods such as SEM, AFM, and TEM, ensuring reproducibility, uniformity, and sub-15 nm precision.
• Quantum transport studies (proof-of-concept): You will conduct low-temperature electronic transport measurements to confirm and characterize fundamental quantum behaviors induced by these nanoscale superlattices.
• Collaboration and documentation: You will closely collaborate with international experts from DTU Physics and DTU NanoLab, sharing knowledge and methodologies, and meticulously document your processes to ensure reproducibility and facilitate future research. 

Qualifications:

A successful candidate will be able to demonstrate some, or all, of the following skills: 

• Proven practical experience with electron-beam lithography or advanced micro/nanofabrication methods.
• Solid understanding and background in condensed matter physics, quantum mechanics, or nanoscale materials science.
• Hands-on laboratory experience with characterization tools (SEM, AFM, TEM) or electronic measurement setups.
• Hands-on laboratory experience with two-dimensional materials such as graphene, α-RuCl₃, and TMDs.
• Excellent command of written and spoken English, along with strong communication skills.
• Ability to independently pursue complex tasks while actively contributing to a collaborative, interdisciplinary research environment.
• Strong motivation to achieve scientific excellence and to contribute significantly to the field of quantum nanotechnology.
