🌟 能否介绍一下您的获奖论文？
In this work we synthesized and studied a twisted bilayer of germanene, the germanium analogue of graphene. By rotating the two layers, we were able to form a moiré pattern, which we mapped its structural and electronic properties using scanning tunnelling microscopy and spectroscopy. We found that the electronic band gap is not uniform across the moiré. It opens in some stacking regions and closes in others, while the edges are metallic. We also observed two clear spectral peaks (van Hove singularities) and used them to extract the charge-carrier velocity. Our tight binding calculations show that an external electric field can switch the system through two different topological phases, making twisted germanene a promising platform for tunable quantum states.
🌟 是什么促使您向2024 Emerging Leaders特辑投稿？
I was invited to submit in this collection. I saw it as an opportunity to show germanene as a versatile platform and to reach a broader community working on moiré and 2D materials.
🌟 获得这一认可，您的感受如何？
It is very rewarding. The recognition validates several years of systematic work on germanene growth and characterization, and it highlights the contributions of the whole team and our collaborators.
🌟 您认为在职业生涯早期获得奖项是否重要？
Yes. I believe that early recognition helps establish scientific credibility and independence, which is important for securing funding, building a group and starting new collaborations. It also affirms that the chosen research direction is promising.
🌟 您接下来的研究和职业规划是什么？
Scientifically, I would like to other twist angles, and apply electric fields to tune the topology in the system systematically. It will be very interesting to bring the van Hove singularities closer to the Fermi level to search for correlated phases. I am also working on germanene nanoribbons which is another system that could provide novel quantum phases to study experimentally.
🌟 您会向其他研究人员推荐Emerging Leaders奖项吗？
I would absolutely encourage other early-career researchers to consider submitting. As the collection could provide good visibility of the work.
