Master of Engineering in Materials Science and Nuclear Engineering, Imperial College London (ICL)(2020).

PhD Ecole Polytechnique «Studies of localized valleytronics in quasi-Janus materials», Condensed Matter Physics, Electrons, Photons, Surfaces Group, supervisors: Alistair Rowe and Fabian Cadiz.



During my master’s project at Imperial College London, I have studied polytypism in halide perovskitesolar cells in the Materials Design Group under the supervision of Prof. Aaron Walsh. The aim of the project was to build a perovskite polytype builder to study and compare the electronic structure ofdifferent perovskite polytypes.

My first research project was in 2019 at Institut Néel in Grenoble, where under the supervision of Dr.Jacek Kasprzak I performed some coherent nonlinear spectroscopy on MoSe2 samples resulting in my first ever publication.

Following this research project, I decided to pursue working on transition metal dichalcogenides (TMDC) with a PhD in physics in the Electrons Photons Surfaces Group (EPS) at the PMC laboratory under the supervision of Dr. Alistair Rowe and Dr. Fabian Cadiz. I am currently studying localized valleytronics in 2D Janus materials.

Was is all
that about?

SO many words for such small objects!

My work consists in studying the properties of the materials that are much thinner than you can imagine. They have only one or a few atomic layers, about a million times thinner than a sheet of paper! So yes, we can say they only have 2 dimensions.

Why are they interesting?

You might have heard of graphene, the miracle 2D material with extraordinary physical properties,chemical tunability, and huge potential for various applications. It has one big flaw, it does not emit light, thus cannot be used for optoelectronic applications. By the way optoelectronics is the branch of technology concerned with the combined use of electronics and light. For example LEDs, photodetectors, LEDs, photovoltaics can enter that category of applications.

It’s so disappointing to see that an incredible material like this one cannot be used to improve optoelectronic applications... but there might be a solution! There is a whole family of 2D materials that absorbs and emits light very efficiently: Transition Metal Dichalcogenides (TMDCs). There has been very little research on them and they seem very promising. So exciting! 

This is why I decided to take up the challenge and explore them, specifically concentrating on an even less known TMD alloys. Lets see what sits in them. You can follow my research on Research Gate where I keep all my articles but if you are interested in more day to day information check up my Instagram and don’t hesitate to message or email. I’m always happy to answer questions or chat to other people as curious as me!
