Hey 🌎? Could you just quiet down a bit? Second quake in 2 weeks. No macroscopic damage, but the STMs do not like the spicy earth. TBH, I’m not really a fan either. 😬

I just got an email from DOE having reviewed for them before. Hard to read and believe the depth of it.

Oh, Sarah Burke is a VERY common name so it’s actually not that easy to track me down! No worries! Thanks very much for adding me!

Thanks! 😊

A few weeks ago we had a lot of fun showing CBC Vancouver's science reporter, Darius Mahdavi, around the Quantum Matter Institute. He *may* have mocked our excessive use of the word quantum (ok, fair!), but put together a great explainer of the world of quantum materials! www.cbc.ca/player/play/...

Got spectra? Sort them with k-means! We used k-means unsupervised clustering to categorize spectra in an electronically inhomogeneous materials, and found it works remarkably well when your eye says "those are different" (not so much otherwise). k-means: just try it! pubs.aip.org/aip/apl/arti...

Two-Stage Growth for Highly Ordered Epitaxial C60 Films on Au(111) As an organic semiconductor and a prototypical acceptor molecule in organic photovoltaics, C60 has broad relevance to the world of organic thin film electronics. Although highly uniform C60 thin films are necessary to conduct spectroscopic analysis of the electronic structure of these C60-based materials, reported C60 films show a relatively low degree of order beyond a monolayer. Here, we develop a generalizable two-stage growth technique that consistently produces single-domain C60 films of controllable thicknesses, using Au(111) as an epitaxially well-matched substrate. We characterize the films using low-energy electron diffraction, low-energy electron microscopy, scanning tunneling microscopy, and angle-resolved photoemission spectroscopy (ARPES). We report highly oriented epitaxial film growth of C60/Au(111) from 1 monolayer (ML) up to 20 ML films. The high-quality of the C60 thin films enables the direct observation of the electronic dispersion of the HOMO and HOMO–1 bands via ARPES without need for small spot sizes. Our results indicate a path for the growth of organic films on metallic substrates with long-range ordering.

Often the solution to getting good data is having good materials! In order to be able to do ARPES on C60 films, we had to work hard on making sure the films were uniform and well ordered. It turned out distilling the first ML was the way to go! Read more here: pubs.acs.org/doi/abs/10.1...

Time to boot up over here… posts on our recent papers and a proper profile and banner coming soon… 🕦

Oh, I did this 3 weeks ago (tripped up concrete stairs) and had bloody knuckles going back into a workshop and for a government official’s tour. 🤦🏻‍♀️ Just healed now. Annoying but could have been worse as you say!
