I am excited to share with you our recent work published today in @NatureNano, where we developed a novel nanolithography method that enables the generation and in-situ readout of a myriad of nanometric topological ferroelectric structures.

The process is automated and highly tunable allowing for multiple structures to be generated, edited, read and erased at a fast pace.
Contact me if you want to try it out in your samples at checam@ornl.gov

Do you want to know how to track drifting ferroelectric domains at the nanoscale in an automated and fast manner?
At @ORNL, we have used fast sparse scanning in combination with compressed sensing image reconstruction to achieve it. Check it out!

Very interrsting talks in the 1st day at #F22MRS!
Come to my talk about electrical mapping with spm tomorrow in the 2nd floor of the Sheraton hotel! Hope to see you there :)

Trabajo en un laboratorio de nanotecnologia americano y usando un microscopio de fuerzas atomicas, acabo de hacer el escudo del @RealBetis mas pequeño (en tamaño) de la historia: 5 micras hace (es decir: 0.005 milimetros). Un saludo a todos los Beticos desde Estados Unidos!

1. We reveal a measurable electromechanical response in CIPS at the paraelectric state.
2. We map the local dielectric response along the ferro/para phase tranisition.
3. We discover an enhanced conductivity at the CIPS/IPS interface.

The second article of my postodc at @ORNL is out! We combined unsupervised learning with multimodal microscopies to unravel phase-specific phononic modes in CIPS/IPS 💪

Trying to use #AFM for #energyreseach?
Here you have our new book chapter on EFM and KPFM modes for it! :)

Happy to know the first paper from my postdoc at @ORNL is out!
Thanks to all the group and specially to my mentor Liam :)
Stay tuned... cause more will come!

In the paper we present an advanced SPM aproach for simultaneous mapping surface potential, dielectric and piezoelectric properties on the nanoscale... and show its capabilities on CuInP2S6 van der Waals layered ferroelectric :)
