Coherent coupling dynamics in a quantum dot microdisk laser
D. K. Young, L. Zhang, D. D. Awschalom +1
Luminescence intensity autocorrelation (LIA) is employed to investigate coupling dynamics between (In,Ga)As QDs and a high-Q (~7000) resonator with ultrafast time resolution (150 f…
Anisotropic Electrical Spin Injection in Ferromagnetic Semiconductor Heterostructures
D. K. Young, E. Johnston-Halperin, D. D. Awschalom +2
A fourteen-fold anisotropy in the spin transport efficiency parallel and perpendicular to the charge transport is observed in a vertically-biased (Ga,Mn)As-based spin-polarized lig…
Spin-polarized Zener tunneling in (Ga,Mn)As
E. Johnston-Halperin, D. Lofgreen, R. K. Kawakami +4
We investigate spin-polarized inter-band tunneling through measurement of (Ga,Mn)As based Zener tunnel diode. By placing the diode under reverse bias, electron spin polarization is…
