The spin splitting arising from H ( 1 ) is, however, expected to be much less than that coming from H ( 2 ), and hence, unlikely to cause any giant RSS (i.e. Considering only the linear-in- k spin splittings, one can show that they can arise due to H ( 1 ) by the use of the first-order PT or the coupling between perturbing terms ℏ m 0 q ⋅ p and H ( 2 ) in the second order PT. Here, V, σ and p denote the crystal potential, Pauli matrices and the momentum operator, respectively, and q = k − k 0. the spin Hall effect and resonance enhanced magneto-optical conductivity. Following these discoveries, attempts have been made to realize RSS in three-dimensional systems, as such systems are expected to be an ideal laboratory for exploring many novel phenomena, e.g. the Bi-covered Ag(111) surface, for which the angle resolved photoemisson spectroscopy (ARPES) has revealed a giant RSS of the order of 200 meV ast. However, there have been a few exceptions, e.g. įor most of these systems, the level of Rashba spin splitting (RSS) are found to be rather small (at most several meV). This effect has been experimentally observed for a number of non-magnetic metallic surfaces lashell ast koroteev and also demonstrated to exist at the interface of the semiconductor hetrostructures nitta. A promising candidate to achieve this goal is so-called Rashba effect, which relies on the spin-orbit interaction (SOI) of the carriers in an inversion ( I) asymmetric environment rashba.
