PDF Rashba Spin Orbit Coupling Enhanced Carrier Lifetime in NH PbI.

Rashba spin-orbit (SO) coupling [3] has been proposed as a mechanism for spin control, not only because of the possibility of its external manipulation, but also because it is the physical origin of spin-dependent phenomena such as anisotropic magnetoresistance [4] and the spin-Hall effect [5]. The Rashba and Dresselhaus types of spin-orbit coupling are two typical linear coupling forms. We establish the fundamental physics of a model which can be viewed as the double version of the. The spin orbit coupling spin torque consists of the field-like [REF: S.G. Tan et al., arXiv:0705.3502, (2007).] and the damping-like terms [REF: H. Kurebayashi et al., Nature Nanotechnology 9, 211 (2014).] that have been widely studied for applications in magnetic memory. We focus, in this article, not on the spin orbit effect producing the above spin torques, but on its magnifying the damping.

We report a theoretical study of the spin and valley dependent transport properties in a WSe 2 superlattice with external Rashba spin-orbit interaction (ERSOI). It is shown that the conductance with and without spin flip strongly depends on the ERSOI and has an oscillatory behavior with respect to ERSOI strength, thus WSe 2 superlattice can act as a spin-converter.

Manipulating the electron spin with the aid of spin-orbit coupling (SOC) is an indispensable element of spintronics. Electrostatically gating a material with strong SOC results in an effective magnetic field which can in turn be used to govern the electron spin.

Spin-orbit-coupled BECs were originally addressed in Refs. [7,8] as examples of unconventional condensation; it was argued in Ref.

More recently, the case of the Rashba-coupled BEC was treated using mean-ﬁeld theory [9] and incorporating.

An important ingredient of the DDT is the spin-orbit coupling of the Rashba [8-10] or Dresselhaus [11,12] types. This Rashba-Dresselhaus (RD) coupling scheme is described by a vector potential which can be made proportional to the spin-1/2 operator of a particle within a plane [13]. Also calculate separately in a k·p formalism the Rashba spin-orbit coupling parameter in silicon quantum wells. This is a key parameter in our calculation as well as for other spin control considerations, both negative and positive. In the next section we discuss the origin and magnitude of the SOC in realistic heterostructures. The section.
