Tunable Rashba Spin Splitting in Two-Dimensional Polar Perovskites
Webb10 dec. 2024 · Rashba spin-split quantum well states, 2D states that develop at the surface of strong spin-orbit coupling materials, are ideal given the tunability of their energy and spin states. Webb5 dec. 2024 · In 1964, Solomon Pekar and Emmanuel Rashba observed that nonuniform magnetization couples the electron spin to its orbital motion. It turns out that, for an electron in a Néel antiferromagnet, a smooth texture of the staggered magnetization also produces spin-orbit coupling. example of wedding vow

The Rashba effect, also called Bychkov–Rashba effect, is a momentum-dependent splitting of spin bands in bulk crystals and low-dimensional condensed matter systems (such as heterostructures and surface states) similar to the splitting of particles and anti-particles in the Dirac Hamiltonian. The splitting … Visa mer The Rashba effect is most easily seen in the simple model Hamiltonian known as the Rashba Hamiltonian $${\displaystyle H_{\rm {R}}=\alpha ({\boldsymbol {\sigma }}\times \mathbf {p} )\cdot {\hat {z}}}$$ Visa mer Spintronics - Electronic devices are based on the ability to manipulate the electrons position by means of electric fields. Similarly, devices can be based on the manipulation of the … Visa mer The Rashba spin-orbit coupling is typical for systems with uniaxial symmetry, e.g., for hexagonal crystals of CdS and CdSe for which it was originally found and perovskites, and also for heterostructures where it develops as a result of a symmetry breaking … Visa mer The Rashba effect is a direct result of inversion symmetry breaking in the direction perpendicular to the two-dimensional plane. … Visa mer In this section we will sketch a method to estimate the coupling constant $${\displaystyle \alpha }$$ from microscopics using a tight-binding model. Typically, the itinerant electrons that form the two-dimensional electron gas (2DEG) originate in atomic s … Visa mer • Electric dipole spin resonance Visa mer 1. ^ More specifically, uniaxial noncentrosymmetric crystals. 2. ^ AMR in most common magnetic materials was reviewed by … Visa mer Webb23 nov. 2016 · The interplay between spin–orbit coupling and two-dimensionality has led to the emergence of new phases of matter, such as spin-polarized surface states in topological insulators, interfacial ...
