Spin-orbit interaction in a two-dimensional electron gas in a InAs/AlSb quantum well with gate-controlled electron density
نویسندگان
چکیده
We present experiments on the tuning of the spin-orbit interaction in a two-dimensional electron gas in an asymmetric InAs/AlSb quantum well using a gate. The observed dependence of the spin splitting energy on the electron density can be attributed solely to the change in the Fermi wave vector. The spin-orbit interaction parameter (a'0.6310 eV m) as such does not change significantly with electron density. @S0163-1829~98!07116-1#

Quantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls
The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...
متن کاملBand hybridization and spin-splitting in InAs/AlSb/GaSb type II and broken-gap quantum wells
We present a detailed theoretical study on the features of band hybridization and zero-field spin-splitting in InAs/AlSb/GaSb quantum wells QWs . An eight-band k ·p approach is developed to calculate the electronic subband structure in such structures. In the absence of the AlSb layer, the hybridized energy gaps can be observed at the anticrossing points between the lowest electron subband and ...
متن کاملTwo-dimensional to three-dimensional tunneling in InAs/AlSb/GaSb quantum well heterojunctions
We examine room temperature band-to-band tunneling in 2D InAs/3D GaSb heterostructures. Specifically, multi-subband, gate-controlled negative differential resistance is observed in InAs/ AlSb/GaSb junctions. Due to spatial confinement in the 10 nm-thick InAs layer, tunneling contributions from two distinct subbands are observed as sharp steps in the current-voltage characteristics. It is shown ...
متن کاملInAlSb/InAs/AlGaSb Quantum Well Heterostructures for High-Electron-Mobility Transistors
Heterostructures for InAs-channel high-electron-mobility transistors (HEMTs) were investigated. Reactive AlSb buffer and barrier layers were replaced by more stable Al0.7Ga0.3Sb and In0.2Al0.8Sb alloys. The distance between the gate and the channel was reduced to 7–13 nm to allow good aspect ratios for very short gate lengths. In addition, n-InAs caps were successfully deposited on the In0.2Al0...
متن کاملA drift-diffusion model for spin-polarized transport in a two-dimensional non-degenerate electron gas controlled by spin–orbit interaction
We apply the Wigner function formalism to derive drift-diffusion transport equations for spin-polarized electrons in a III–V semiconductor single quantum well. The electron spin dynamics is controlled by the spin–orbit interaction which is linear in the momentum. In the transport regime studied, the electron momentum scattering rate is appreciably faster than the spin dynamics. A set of transpo...
