Post-Doc: Spin-Injection And Detection In 2D Materials
Description of the offer :
In strong analogy to graphene, the physical properties of transition metal dichalcogenides (TMDCs) change drastically when thinning the bulk material down to one monolayer (ML). The closely related ML materials MoS2, MoSe2, WSe2 and WS2 have a direct bandgap in the visible region and show strong optical absorption (> 10%/ML). In addition, ML TMDCs provide unique and convenient access to control the electron spin and valley degrees of freedom in k-space in the emerging field of ''Valleytronics''. The goal of the post-doc subject is to study the spin-injection and detection in 2D material heterostructure (pn junction, lateral and vertical structures…). Different methods will be used, either electric spin-injection with optic spin-detection (spin-LED) or optic spin-injection with electric spin-detection (spin photodiode).
The post-doc candidate will work in the “Nanomaterial for optics” team at Institut Jean Lamour (IJL, France), where is internationally recognized for its expertise in semiconductor spintronics. The group has abundant experience in electron spin injection and detection in semiconductors. The study will also benefit from the multi-UHV chamber interconnected platform TUBE in IJL, where allows to fabricate divers structure and make in-situ characterization without breaking the vacuum.
The position will be opened from 1st October 2019 with a duration of 18 months. The net salary will be around 2000-2200 euros/month (exact amount of salary will depend on his/her experience after thesis).[ ]
