Bias dependence of spin injection into GaAs from Fe, FeCo, and (Ga,Mn)As contacts
Spin injection from Fe(001) and (Ga,Mn)As(001) into n-GaAs(001) was investigated using a method which provides two-dimensional cross-sectional images of the spin polarization in GaAs. While the distribution of the spin polarization below the injecting contact is nearly uniform for (Ga,Mn)As, a strong confinement near the contact edge is observed for Fe and FeCo. The spin polarization in GaAs ch...
متن کاملBallistic spin injection from Fe„001... into ZnSe and GaAs
We consider the spin injection from Fe into ZnSe and GaAs in the ballistic limit. By means of the ab initio screened Korringa-Kohn-Rostoker method we calculate the ground-state properties of epitaxial FeuZnSe(001) and FeuGaAs(001) heterostructures. Three injection processes are considered: injection of hot electrons and injection of ‘‘thermal’’ electrons with and without an interface barrier. T...
متن کاملRoom-temperature spin injection from Fe into GaAs.
Injection of spin polarized electrons from a metal into a semiconductor is demonstrated for a GaAs/(In,Ga)As light emitting diode covered with Fe. The circular polarization degree of the observed electroluminescence reveals a spin injection efficiency of 2%. The underlying injection mechanism is explained in terms of a tunneling process.
متن کاملSpin transport through GaAs/GaMnAs/GaAs
This work addresses spin-dependent transport in the heterostructure p-GaAs/GaMnAs/p-GaAs. The diluted ferromagnetic semiconductor GaMnAs layer behaves, within mean field approximation, as a potential well for spin-down carriers and a potential barrier for spin-up ones. Thus the transport would be spin-dependent. The goal of this work is to devise spin filters relevant for spin-dependent optoele...
متن کاملan investigation into iranian teachers consistency and bias in evaluation of students writings
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
