TLDR
A comprehensive review of spin-polarized light-emitting diodes and surface emitting lasers is provided in this paper, concluding with a discussion of future prospects and operation principles and design of spinpolarised light sources.Abstract:
Spin-polarized light sources are a new class of devices in which the radiative recombination of spin-polarized carriers results in luminescence exhibiting a net circular polarization. The operation principles and design of spin-polarized light sources are discussed. A comprehensive review of experimental work on spin-polarized light-emitting diodes and surface-emitting lasers is provided, concluding with a discussion of future prospects.read more

Semiconductor Spintronics
TL;DR: Spintronics refers commonly to phenomena in which the spin of electrons in a solid state environment plays the determining role as mentioned in this paper, and is an emerging research field of electronics: spintronics devices are based on a spin control of electronics, or on an electrical and optical control of spin or magnetism.

David Giovanni,Hong Ma,Hong Ma,Julianto Chua,Michael Grätzel,Michael Grätzel,Ramamoorthy Ramesh,Subodh Mhaisalkar,Nripan Mathews,Tze Chien Sum +9 more
TL;DR: This work highlights the potential of CH3NH3PbI3 as a new candidate for ultrafast spin switches in spintronics applications and elucidates the electron spin relaxation lifetime to be ∼7 ps and that of the hole is ∼1 ps through a simple two-level model.

Analytical model of spin-polarized semiconductor lasers
TL;DR: In this paper, an analytical model for semiconductor lasers with injection (pump) of spin-polarized electrons, allowing them to systematically investigate different operating regimes, is presented. And the maximum threshold reduction by electrically pumped spin-Polarized carriers is larger than previously thought possible and can be enhanced by ultrafast spin relaxation of holes.
