Origin and evolution of surface spin current in topological insulators
André Dankert, Priyamvada Bhaskar, Dmitrii Khokhriakov +6
The Dirac surface states of topological insulators offer a unique possibility for creating spin polarized charge currents due to the spin-momentum locking. Here we demonstrate that…
Spin-Polarized Tunneling through Chemical Vapor Deposited Multilayer Molybdenum Disulfide
André Dankert, Parham Pashaei, M. Venkata Kamalakar +10
The two-dimensional (2D) semiconductor molybdenum disulfide (MoS2) has attracted widespread attention for its extraordinary electrical, optical, spin and valley related properties.…
Hall sensors batch-fabricated on all-CVD h-BN/graphene/h-BN heterostructures
André Dankert, Bogdan Karpiak, Saroj P. Dash
The two-dimensional (2D) material graphene is highly promising for Hall sensors due to its potential of having high charge carrier mobility and low carrier concentration at room te…
Gate-tunable Hall sensors on large area CVD graphene protected by h-BN with 1D edge contacts
Bogdan Karpiak, André Dankert, Saroj P. Dash
Graphene is an excellent material for Hall sensors due to its atomically thin structure, high carrier mobility and low carrier density. However, graphene devices need to be protect…
One-dimensional ferromagnetic edge contacts to two-dimensional graphene/h-BN heterostructures
Bogdan Karpiak, André Dankert, Aron W. Cummings +3
We report the fabrication of one-dimensional (1D) ferromagnetic edge contacts to two-dimensional (2D) graphene/h-BN heterostructures. While aiming to study spin injection/detection…
Resistivity Anomaly in Weyl Semimetal candidate Molybdenum Telluride
Dhavala Suri, Christopher Linderalv, Bogdan Karpiak +8
The Weyl semi-metal candidate MoTe is expected to exhibit a range of exotic electronic transport properties. It exhibits a structural phase transition near room temperature t…
