About alejandro

Alejandro is a Research Fellow at INL, and he works in the group of Joaquín Fernández-Rossier, Theory of Quantum Nanostructures. He holds a PhD degree in Physics from the University of Valencia. After, Alejandro was a postdoctoral researcher at the Institute of Electronics, Microelectronics and Nanotechnology in Lille, France. In 2012 he joined the University of Luxembourg as a post-doc and from 2014-2017 was the PI of the research line focused on spectroscopy of 2D materials, funded with a CORE Junior grant. From 2017 to 2019 he worked at the Institute of Materials Science of the University of Valencia with a Juan de la Cierva fellowship. He is the author of more than 30 papers in international peer-reviewed journals of high impact factor such as Nano Letters, Physical Review Letters, Physical Review B, 2D Materials or New Journal of Physics. Out of the lab, he likes to spend time with family, friends and playing rugby.

 

 

The Cofund project

The project “Two-dimensional Ferromagnetic Materials for designing of quantum nanodevices” aims to design nanodevices built of 2D materials suitable for spintronics and valleytronics, using novel functional materials based in ferromagnetic and semiconducting two-dimensional materials.

Nowadays, the technology services used at houses and industry require to process a larger amount of information faster and faster. Advanced materials can provide new functionalities to manage intense data traffic and at the same time, lower the manufacturing costs and energy consumption. On these grounds, the replacement of the electron charge (electronics) by the spin (spintronics) or other carriers of information like the valley (valleytronics) is a promising approach to reduce the losses in the transport of information, design devices able to be useful in quantum computing, and in general, make more energy-efficient devices.

The discovery of ferromagnetic insulating two-dimensional materials has increased the palette of available 2D materials for optoelectronics applications, including now 2D multiferroic materials [1]. These new 2D materials have intrinsic magnetic order and open the way to use 2D materials in spintronics, topological devices, or data storage applications, and they are a potential key resource for the next generation of nanodevices [2].

Our research is in the realm of theory and calculations of properties of 2D materials. This project will perform calculations using different methods according to the complexity of the system and the required accuracy. Most of the calculations will be done with ab initio methods with different levels of complexity.
