DESCRIPTION:Speaker: Avsar Ahmet\nhosted by Onur Hosten\nAbstract: Abstract
 : van der Waals heterostructure devices\, composed from the assembly of 2D
  crystals\, could enable new spintronics functionalities that are not acce
 ssible in individual crystals or any other bulk materials [1]. In this tal
 k\, I will present our spin dependent electronic transport measurements in
  such ultra-thin devices. Firstly\, I will demonstrate that by bringing se
 mi-metallic graphene into a proximity to transition metal dichalcogenides\
 , we enhance its weak spin orbit coupling strength three orders of magnitu
 de [2] and simultaneously realize optospintronics functionality [3]. Then\
 , I will show that semiconducting black phosphorus-based van der Waals het
 erostructures exhibit remarkable spin transport properties [4]after an in-
 situ h-BN encapsulation process [5]. Finally\, I will provide an outlook a
 bout 2D van der Waals spin devices after briefly reviewing recently discov
 ered 2D magnets [6].[1] Novoselov\, K. S.\, Mishchenko\, A.\, Carvalho\, A
