Spin Dynamics In Two-dimensional Quantum Materials A Theoretical Study - Marc Vila Tusell - Paperback - en Book

This Thesis Focuses On The Exploration Of Nontrivial Spin Dynamics In Graphene-based Devices And Topological Materials, Using Realistic Theoretical Models And State-of-the-art Quantum Transport Methodologies. The Main Outcomes Of This Work Are: (i) The Analysis Of The Crossover From Diffusive To Ballistic Spin Transport Regimes In Ultraclean Graphene Nonlocal Devices, And (ii) Investigation Of Spin Transport And Spin Dynamics Phenomena (such As The (quantum) Spin Hall Effect) In Novel Topological Materials, Such As Monolayer Weyl Semimetals Wete2 And Mote2. Indeed, The Ballistic Spin Transport Results Are Key For Further Interpretation Of Ultraclean Spintronic Devices, And Will Enable Extracting Precise Values Of Spin Diffusion Lengths In Diffusive Transport And Guide Experiments In The (quasi)ballistic Regime.
