Streszczenie

Spintronics has made important contributions to electronic devices, fundamentally in the fields on magnetic recording and non-volatile random-access memories. More recently, post-CMOS applications, such as the MESO one from Intel, aim to integrate logic and memory in spin-based devices. A key player in this proposal is the spin-to-charge conversion, which permits to electrically create and detect pure spin currents without using ferromagnetic materials.

In the initial part of the talk, I will briefly present the status of the experimental realization of the MESO proposal, focusing particularly on the readout of the spin memory state. In the main part of the talk, I will show how low symmetry materials can add new possibilities to spin-to-charge conversion. Moving beyond single crystalline materials such as chiral Tellurium, I will show how twisted, low symmetry, graphene/chalcogenide structures display a complex spin texture and charge-to-spin conversion effects that could allow us to move beyond devices with standard metallic layers.
