Defect passivation for two-dimensional (2D) magnetic semiconductors

Project description

Optimising electronic properties of 2D magnetic semiconductors through strategic defect passivation

2D magnetic semiconductors are materials with magnetic properties and semiconducting behaviour in 2D structures. These unique characteristics enable them to control charge and spin degrees of freedom, offering a unique platform for investigating advanced device architectures and exploring novel physical phenomena. Among such materials, 2D van der Waals chromium sulphide bromide (CrSBr) is of particular interest owing to its strong coupling between magnetic and electronic structures. However, its advancement requires insight into defect mechanisms and subsequent passivation strategies. With the support of the Marie Skłodowska-Curie Actions programme, the Defect M project aims to develop a novel chemical passivation approach to achieve high-quality and stable 2D CrSBr. Using a multidisciplinary approach, it will explore degradation mechanisms and spin and charge-based phenomena of 2D CrSBr.

Objective

The unique integration of magnetic and semiconducting properties in 2D magnetic semiconductors opens new opportunities for controlling charge and spin degrees of freedom, crucial for developing advanced spin-based technologies. Among these materials, 2D van der Waals CrSBr stands out due to its strong coupling between magnetic and electronic structures. However, the unexplored passivation strategies and unclear defect mechanisms hinder its advancement for nanoscale opto-spintronic devices. Defect M is designed to establish innovative chemical passivation methodologies to achieve high-quality and stable 2D CrSBr with a comprehensive understanding of defect physics, which not only allows us to gain a better understanding of the degradation mechanism but is also critical to enable reliable studies of spin- and charge-based phenomena. This highly interdisciplinary project facing key future technologies will pave the way for next-generation spin-based devices and benefit the upcoming EU's priorities of digital transformation and green transition.
