New funding: PhD and Postdoctoral positions are available!

Our group has recently received two Singapore MOE Tier 2 grants to support our research on ultraclean electronic systems and novel twisted superlattices.
We are therefore looking for talented and motivated researchers to join our group and study the electronic and mechanical properties of 2D materials and moiré superlattices.

We welcome applications from candidates with backgrounds in areas such as:

• A relevant undergraduate or postgraduate degree in physics, materials science, electrical engineering, or a related field.
• Experience in nanofabrication and van der Waals heterostructure assembly.
• Experience in electronic and/or mechanical measurements of 2D materials, including work with cryogenic eqipment.
• For postdoctoral applicants, a strong research track record and strong reference letters from relevant research groups.

Both PhD and Postdoctoral Research Fellow positions are available.

Congratulations to Amoz on winning the Best Poster Presentation Award!

At the recent MatterX 2026: MSE NUS Annual Research Congress, Amoz received the Best Poster Presentation Award for work carried out during his time in our group.
Congratulations, Amoz, on this well-deserved recognition!

Coulomb screening of superconductivity in magic-angle graphene

Our group has significantly contributed to a new study showing that superconductivity in magic-angle TBG is driven by strong electron–electron interactions. Building on our approach to creating electronically decoupled graphene systems using a large twist angle, while keeping the layers in atomic proximity (see our earlier Nature Communications work: https://www.nature.com/articles/s41467-025-62492-5), we designed an experiment in which a screening TBG layer is placed directly on top of magic-angle TBG.
By tuning the carrier density in the screening layer, we were able to strongly modify — and eventually completely suppress — superconductivity in the magic-angle TBG. This provides direct evidence for the crucial role of electron–electron interactions in the superconducting state.

Congratulations to all our colleagues involved in this work, including Dr Julien Barrier, Dr Liangtao Peng, Prof. Shaffique Adam, Prof. Andre Geim, and many others!
It took significant effort, including quite a battle with the referees, but we made it! 😊

Amoz Chua and Mahesh Hingankar have just joined our group as PhD students!

Both are extremely capable and self-driven researchers, and we are very happy to have them on board. Let’s wish them a successful and exciting PhD journey!
And remember: a PhD is a marathon, not a sprint — but you still need to run fast. 😊

Intrinsic tunnelling revealed by ultraclean heterostructures
Together with Prof. Mario Lanza and collaborators, our group has probed the intrinsic tunnelling limits of 2D insulators and semiconductors.

Using our recently developed Mica Method for polymer-free van der Waals assembly (Nature Communications), we fabricated ultraclean heterostructures that allowed us to access the pristine electronic properties of these materials and reveal their intrinsic tunnelling behaviour.

The work has now been published in Nature Materials.

Searching for papers and keeping up with arXiv just became easier

Our group member, Ian Babich, has developed a new service for scientific literature search and personalized paper discovery.
It significantly outperforms general-purpose AI agents such as Claude and ChatGPT in finding relevant scientific literature and provides daily recommendations of newly published arXiv preprints and peer-reviewed journal papers. You can pair it with you telegram.
Check it out yourself — it is currently free to use!

Congratulations to Krishna!

Our former group member, Dr Krishna Prasad Bera, got an Assistant Professor position at the School of Advanced Sciences (SAS-PHYSICS), Vellore Institute of Technology (VIT), India. We wish him a successful start, and a lot of interesting results in future!

Congratulations to Amoz!

Amoz, who has been carrying out his Final Year Project at NUS, has been awarded multiple prestigious medals:

• Lee Kuan Yew Gold Medal — awarded to the best graduate throughout the course of study
• IES Gold Medal — awarded to the top graduating student
• Materials Research Society (Singapore) Medal — awarded to the top student in the course

These awards are very well deserved and reflect Amoz’s dedication, hard work, and commitment to excellence.
We wish him continued success and hope he maintains the same drive and enthusiasm as he builds a successful research career. Congratulations, Amoz!

Our group has developed a novel polymer-free approach for stacking van der Waals crystals

In this work, we introduce a new stacking method that uses thin mica crystals to assemble van der Waals heterostructures. The concept is simple and elegant: why use polymers to handle van der Waals materials if we can simply use another van der Waals material instead?
This approach enables relatively straightforward fabrication of heterostructures with ultraclean interfaces and surfaces, with the potential to improve device performance across many areas of 2D materials research.
For more details, see our paper in Nature Communications:
https://www.nature.com/articles/s41467-026-72554-x

We are also open to collaborations. If you are interested in learning and applying this method in your own research, please feel free to get in touch.

Welcome Weijie!
Weijie Lu is joining our group as a PhD student at NUS! We wish him a lot of interesting results, and a lot of patience with his future experiments. =)
