A story about resonantly enhancing near-fields to measure the conductivity of single nanowires - enjoyable collaboration with @UfPhotonicsUCL, @OxfordPhysics, @JoyceGroup_ and more! pubs.acs.org/doi/10.1021/ac…

Great news! Our latest results have been published in @NaturePhotonics. We developed an approach based on ultrafast near-field microscopy to simultaneously probe the nanoscale structure and ultrafast carrier dynamics in metal halide perovskites nature.com/articles/s4156…

Happy to announce our latest work has been published in @NaturePhotonics. We have developed a method based on ultrafast near-field microscopy to study the interplay between the nanoscale structure and ultrafast carrier dynamics in metal halide perovskites. nature.com/articles/s4156…

Do you want to fight climate change? Then you should build better solar cells! For this, perovskites are setting new records, but why? Happy to see my colleagues investigate that question with nanoscale spatial and subcycle temporal resolution: nature.com/articles/s4156…

My dear colleagues from @Huber_Group at @uni_regensburg have recently explored diffusion in metal halide perovskites! Their results have been published today in @NaturePhotonics! 🥳 Congratulations on a fantastic paper! 🔗Links: nature.com/articles/s4156… or rdcu.be/dN4ME

Using ultrafast THz nanoscopy, we resolved the interplay between surface morphology, crystallographic phase, and vertical carrier dynamics in metal halide perovskites. Fantastic collaboration with Michael Johnston's group @UniofOxford. @NaturePhotonics nature.com/articles/s4156…

Excited to share that our results on diffusion in metal halide perovskites have been published in @NaturePhotonics 🥳

Nature research paper: All-optical subcycle microscopy on atomic length scales go.nature.com/3y7sh1f

It is a great pleasure to see the hard work of my colleagues and friends finally published! If you have ever wondered what the subcycle structure of atomically confined tunnel currents looks like, you should take a look at this amazing work: nature.com/articles/s4158…

Unlocking the power of tunnelling electrons for ultrafast optical microscopy, now zooming in at the atomic scale! See for yourself: nature.com/articles/s4158…

The time is finally coming that it's possible now to look at the subcycle dynamics at atomic scale, pushing the experimental boundaries much further to higher spatial and temporal resolutions! Congratulations to my colleagues in Regensburg for the amazing achievement!

As well, we wrote a little briefing which gives a bit of an overview! nature.com/articles/d4158…

We have discovered a quantum-mechanical contrast mechanism that enables all-optical microscopy to achieve atomic resolution while retaining subcycle precision. This new concept allows us to trace electrons on their intrinsic length and time scales. nature.com/articles/s4158…

Our latest results have just been published 🥳 Please check out how we have brought all-optical microscopy to the atomic scale. nature.com/articles/s4158…

Some work from my time in Regensburg, in the @Huber_Group. We worked out how to measure the coherent emission from tunnelling electrons, this lets us do ultrafast optical microscopy now at the atomic scale! nature.com/articles/s4158…

@Johannes_Hayes 🥳

It is here! The result of years of hard work together with a great team.🥳🥳 Check out how we were able to bring optical microscopy to the atomic scale and use this to sample subcycle tunnelling currents directly in the time domain: nature.com/articles/s4158…
