Spin-Lasers: Spintronics Beyond Magnetoresistance
Igor Žutić, Gaofeng Xu, Markus Lindemann +7
Introducing spin-polarized carriers in semiconductor lasers reveals an alternative path to realize room-temperature spintronic applications, beyond the usual magnetoresistive effec…
Interplay of resonant states and Landau levels in functionalized graphene
Jeongsu Lee, Denis Kochan, Jaroslav Fabian
Adsorbates can drastically alter physical properties of graphene. Particularly important are adatoms and admolecules that induce resonances at the Dirac point. Such resonances limi…
Resonant scattering due to adatoms in graphene: top, bridge, and hollow position
Susanne Irmer, Denis Kochan, Jeongsu Lee +1
We present a theoretical study of resonance characteristics in graphene from adatoms with or character binding in top, bridge, and hollow positions. The adatoms are descr…
Magnetotransport signatures of the proximity exchange and spin-orbit couplings in graphene
Jeongsu Lee, Jaroslav Fabian
Graphene on an insulating ferromagnetic substrate---ferromagnetic insulator or ferromagnetic metal with a tunnel barrier---is expected to exhibit giant proximity exchange and spin-…
Toward high-frequency operation of spin lasers
Paulo E. Faria Junior, Gaofeng Xu, Jeongsu Lee +3
Injecting spin-polarized carriers into semiconductor lasers provides important opportunities to extend what is known about spintronic devices, as well as to overcome many limitatio…
Nodal "ground states" and orbital textures in semiconductor quantum dots
Jeongsu Lee, Karel Výborný, Jong E. Han +1
Conventional understanding implies that the ground state of a nonmagnetic quantum mechanical system should be nodeless. While this notion also provides a valuable guidance in under…
Systematic study of magnetic linear dichroism and birefringence in (Ga,Mn)As
N. Tesarova, T. Ostatnicky, V. Novak +12
Magnetic linear dichroism and birefringence in (Ga,Mn)As epitaxial layers is investigated by measuring the polarization plane rotation of reflected linearly polarized light when ma…
Tailoring Chirp in Spin-Lasers
Guilhem Boeris, Jeongsu Lee, Karel Vyborny +1
The usefulness of semiconductor lasers is often limited by the undesired frequency modulation, or chirp, a direct consequence of the intensity modulation and carrier dependence of…
Mapping between quantum dot and quantum well lasers: From conventional to spin lasers
Jeongsu Lee, Rafał Oszwałdowski, Christian Gøthgen +1
We explore similarities between the quantum wells and quantum dots used as optical gain media in semiconductor lasers. We formulate a mapping procedure which allows a simpler, ofte…
Spin Modulation in Semiconductor Lasers
Jeongsu Lee, William Falls, Rafal Oszwaldowski +1
We provide an analytic study of the dynamics of semiconductor lasers with injection (pump) of spin-polarized electrons, previously considered in the steady-state regime. Using comp…
