Abstract Details: Van der Waals heterostructure devices, composed from 2D crystals, could enable new spintronics functionalities that are not accessible in individual crystals or any other bulk materials. In this talk, I will present our spin dependent (opto) electronic transport measurements in such hetero devices. Firstly, I will discuss our results on inducing optospintronics functionality in semi-metallic graphene by bringing it in a proximity to monolayer WSe2. Then, I will show that semiconducting black phosphorus-based van der Waals heterostructures exhibit remarkable spin transport properties after an in-situ h-BN encapsulation process. Finally, I will provide an outlook about 2D van der Waals spin devices after briefly reviewing recently discovered 2D magnets.
