Charge-to-spin conversion in chiral monoatomic Te chains investigated using relativistic cylindrical waves technique

Abstract

Using the relativistic symmetrized linearized augmented cylindrical waves method, we investigated electronic and spin states and transport properties of the chiral monoatomic Te chains. The qualitative assessments of spin conductivity and selectivity are obtained under the assumption that the electrons of boundary spin states located at the edges of valence and conduction bands take part in the spin and charge transfer and that the probability of electron tunneling is higher with parallel orientation of the electron spin and chirality vectors of material compared to the case of their antiparallel orientation. The chains are promising for the creation of spin currents and filters and applications in spintronics.
