Optoelectronic Devices Based on Monolayer Transition Metal Dichalcogenides

Oriol López Sánchez

Monolayer transition metal dichalcogenides (TMD) such as molybdenum disulfide (MoS2), tungsten diselenide (WSe2) and tungsten disulfide (WS2), have shown in the last years remarkable physical properties. These direct badgap three-atoms thick monolayers, wi ...

Disentangling bulk and surface Rashba effects in ferroelectric alpha-GeTe

Jan Hugo Dil, Stefan Peter Muff

Macroscopic ferroelectric order in alpha-GeTe with its noncentrosymmetric lattice structure leads to a giant Rashba spin splitting in the bulk bands due to strong spin-orbit interaction. Direct measurements of the bulk band structure using soft x-ray angle ...

Linear response to a heat-driven spin torque

Jean-Philippe Ansermet, Haiming Yu, Francesco Antonio Vetrò, Christian Caspers, Lucas Fitoussi

The existence of a heat-driven spin torque is demonstrated using Co/Cu/Co spin valves embedded in metallic nanowires. Heat currents flowing in one direction or its opposite were obtained by heating optically one end or the other of the nanowires. The spin ...

Opto-spintronics in InP using ferromagnetic tunnel spin filters

Jean-Philippe Ansermet, Murari Soundararajan, Christian Caspers, Dongyoung Yoon

We demonstrate opto-spintronics using Fe-doped Indium Phosphide (InP). The method is based on optical orientation of InP conduction electron spins which are electrically detected in planar InP/oxide/Ni tunnel spin filters. We separate the optical excitatio ...

Spin filter effect in iron oxide nanocrystal arrays

Raffaella Buonsanti

Integrating nanocrystals (NCs) into magnetic tunnel structures is of considerable interest due to expectation of novel properties from their spin selective transport and single electron features. Superstructures by colloidal NCs having translational and or ...
