Tom Siday

I have funding for at least one (hopefully more!) PhD projects starting next October - If you know anyone who might be interested, please share it with them! Thank you 🙏 findaphd.com/phds/?Keywords….

🔓 #OpenAccess: "Resonance-Amplified Terahertz Near-Field Spectroscopy of a Single Nanowire" by Norman, Chu, Peng, Seddon, Hale, Tan, Jagadish, Mouthaan, Alexander-Webber, Joyce, Johnston, Mitrofanov, & @tomsiday go.acs.org/bWZ

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…

Don't forget to submit your manuscript to our #NanoscaleAdvances collection focusing on quantum dynamics! Guest Edited by @KRusimova, @tomsiday and @MarcelRighet Submit your manuscript by 1 April 2025 blogs.rsc.org/nr/2024/08/20/…

A paper on metal halide perovskites from time in @Huber_Group and in Oxford, just published in Nature Photonics We use ultrafast nanoscopy to see structural modes on the nanoscale as well as ultrafast charge carrier motion! nature.com/articles/s4156…

@MarcelRighet Thank you for your kind words Dr Righetto

Finally we can see little things happening quickly! Congrats @tomsiday

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

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

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…

Beautiful new work from friends in Regensburg @Huber_Group, who were able to see - in a single defect! - how ultrafast atomic motion shifts energy levels. nature.com/articles/s4156…

Tailored nanofaceting in InAs nanowires engineer THZ photodetection modes, a lively collaboration with M Johnston and @KunPeng25843400 @OxfordPhysics; @NickForScience @ValerioPiazzaVP @didemdedee @Materials_EPFL @EPFLEngineering rdcu.be/duX2X

The Aharanov-Bohm effect Weisskopf said: The first reaction to this work is that it is wrong; the second is that it is obvious Ehrenberg said: Ach Hiley, zis AB effect that you are discussing, is it the one that Siday and I discovered? What is it? 1/9 🧵

Are you working on new semiconductors for solar energy applications? Chip in with an oral abstract for our #NextGenSolar symposium at MATSUS-24 in sunny Barcelona. Deadline for oral presentations on Wednesday 22nd, submit now! 👇 nanoge.org/MATSUS24/home#…

@MarcelRighet @GroupHerz I've been waiting all day for this! I'll get started alloying them now. thanks Dr Righetto!

Planning to alloy your double halide perovskites? Be careful! We demonstrated how alloying hinders the transport of localised charge carriers. More details in our recently published paper on this 👇 doi.org/10.1021/acs.jp… @GroupHerz

🔬Our work on AgBiS2 NCs is out! Disorder, often considered as a detrimental, turns into an asset when controlled. We show how cation-disorder engineering surprisingly boosts charge-carrier transport. doi.org/10.1002/adma.2… @GroupHerz @OxfordPhysics

We observed the ultrafast emergence of a Floquet-Bloch band structure for the first time. Strong-field #ARPES revealed that Floquet-Bloch states form already after a single optical cycle. The results have been published in @Nature: doi.org/10.1038/s41586…

Highly recommended!

Together with @UMengineering, we realized a stopwatch for delocalized Bloch electrons in crystals that achieves attosecond precision. This way, many-body correlations can be directly measured. Our results were published in @Nature. nature.com/articles/s4158…

The latest issue of Nano Letters is live! On the cover: "Ultrafast Nanoscopy of High-Density Exciton Phases in WSe2" @Huber_Group @MalicGroup   Learn more: go.acs.org/JM

In collaboration with @MalicGroup, we used ultrafast near-field microscopy to study the Mott transition of strongly-bound excitons in an atomically thin heterostructure of WSe₂. pubs.acs.org/doi/10.1021/ac…
