Spin-injection and spin-relaxation in p-doped InGaAs/GaAs quantum-dot spin light emitting diode at zero magnetic field
Alaa E. Giba, Xue Gao, Mathieu Stoffel +10
We report on efficient spin injection in p-doped InGaAs/GaAs quantum-dot (QD) spin light emitting diode (spin-LED) under zero applied magnetic field. A high degree of electrolumine…
Electrical spin injection into InGaAs/GaAs quantum wells: a comparison between MgO tunnel barriers grown by sputtering and molecular beam epitaxy methods
P. Barate, S. Liang, T. T. Zhang +16
An efficient electrical spin injection into an InGaAs/GaAs quantum well light emitting diode is demonstrated thanks to a CoFeB/MgO spin injector. The textured MgO tunnel barrier is…
Electrical initialization of electron and nuclear spins in a single quantum dot at zero magnetic field
F. Cadiz, A. Djeffal, D. Lagarde +18
The emission of circularly polarized light from a single quantum dot relies on the injection of carriers with well-defined spin polarization. Here we demonstrate single dot electro…
Possible atomic structures for the sub-bandgap absorption of chalcogen hyperdoped silicon
Ke-Fan Wang, Hezhu Shao, Kong Liu +3
Single-crystal silicon wafers were hyperdoped respectively by sulfur, selenium, and tellurium element using ion implantation and nanosecond laser melting. The hyperdoping of such c…
Research progress of electronic properties of self-assembled semiconductor quantum dots
Jie Sun, Peng Jin, Zhanguo Wang
Self-assembled semiconductor quantum dot is a new type of artificially designed and grown function material which exhibits quantum size effect, quantum interference effect, surface…
Electron resonant tunneling through InAs/GaAs quantum dots embedded in a Schottky diode with an AlAs insertion layer
Jie Sun, Peng Jin, Chang Zhao +5
Molecular beam epitaxy is employed to manufacture self-assembled InAs/GaAs quantum dot Schottky resonant tunneling diodes. By virtue of a thin AlAs insertion barrier, the thermal c…
