Title: Electric Field-Controlled Magnetization in GaAs/AlGaAs Heterostructures–Chiral Organic Molecules Hybrids

Abstract

Here, we study GaAs/AlGaAs devices hostinga two-dimensional electron gas and coated with a monolayer of chiral organic molecules.We observe clear signatures of room temperature magnetism, which is induced in these systems by applying a gate voltage. We explain this phenomenon as a consequence of the spin-polarized charges that are injectedinto the semiconductor through the chiral molecules. The orientation of the magnetic moment can be manipulated by low gate voltages, with a switching ratein the MHz range. Therefore, our devices implement an efficient, electric field controlled magnetization, which has long been desired for their technical prospects.

Large linear magnetoresistance in a GaAs/AlGaAs heterostructure

Journal Article Aamir, Mohammed Ali, E-mail: aamir@physics.iisc.ernet.in ; Goswami, Srijit ; Ghosh, Arindam ; ... - AIP Conference Proceedings

We report non-saturating linear magnetoresistance (MR) in a two-dimensional electron system (2DES) at a GaAs/AlGaAs heterointerface in the strongly insulating regime. We achieve this by driving the gate voltage below the pinch-off point of the device and operating it in the non-equilibrium regime with high source-drain bias. Remarkably, the magnitude of MR is as large as 500% per Tesla with respect to resistance at zero magnetic field, thus dwarfing most non-magnetic materials which exhibit this linearity. Its primary advantage over most other materials is that both linearity and the enormous magnitude are retained over a broad temperature range (0.3 Kmore »« less

Hybrid architecture for shallow accumulation mode AlGaAs/GaAs heterostructures with epitaxial gates

Journal Article MacLeod, S. J. ; See, A. M. ; Hamilton, A. R., E-mail: Alex.Hamilton@unsw.edu.au ; ... - Applied Physics Letters

Accumulation mode devices with epitaxially grown gates have excellent electrical stability due to the absence of dopant impurities and surface states. We overcome typical fabrication issues associated with epitaxially gated structures (e.g., gate leakage and high contact resistance) by using separate gates to control the electron densities in the Ohmic and Hall bar regions. This hybrid gate architecture opens up a way to make ultrastable nanoscale devices where the separation between the surface gates and the 2D electron gas is small. In this work, we demonstrate that the hybrid devices made from the same wafer have reproducible electrical characteristics, withmore »« less

Plasmonic terahertz detectors based on a high-electron mobility GaAs/AlGaAs heterostructure

Journal Article Białek, M., E-mail: marcin.bialek@fuw.edu.pl ; Witowski, A. M. ; Grynberg, M. ; ... - Journal of Applied Physics

In order to characterize magnetic field (B) tunable THz plasmonic detectors, spectroscopy experiments were carried out at liquid helium temperatures and high magnetic fields on devices fabricated on a high electron mobility GaAs/AlGaAs heterostructure. The samples were either gated (the gate of a meander shape) or ungated. Spectra of a photovoltage generated by THz radiation were obtained as a function of B at a fixed THz excitation from a THz laser or as a function of THz photon frequency at a fixed B with a Fourier spectrometer. In the first type of measurements, the wave vector of magnetoplasmons excited wasmore »« less

Fabrication and Characterization of a Single Hole Transistor in p-type GaAs/AlGaAs Heterostructures

Technical Report Tracy, Lisa A ; Reno, John L. ; Hargett, Terry W.

Most spin qubit research to date has focused on manipulating single electron spins in quantum dots. However, hole spins are predicted to have some advantages over electron spins, such as reduced coupling to host semiconductor nuclear spins and the ability to control hole spins electrically using the large spin-orbit interaction. Building on recent advances in fabricating high-mobility 2D hole systems in GaAs/AlGaAs heterostructures at Sandia, we fabricate and characterize single hole transistors in GaAs. We demonstrate p-type double quantum dot devices with few-hole occupation, which could be used to study the physics of individual hole spins and control over couplingmore »« less

Fabrication and characterization of an undoped GaAs/AlGaAs quantum dot device

Journal Article Li, Hai-Ou ; Cao, Gang ; Xiao, Ming ; ... - Journal of Applied Physics

We demonstrate the development of a double quantum dot with an integrated charge sensor fabricated in undoped GaAs/AlGaAs heterostructures using a double top-gated design. Based on the evaluation of the integrated charge sensor, the double quantum dot can be tuned to a few-electron region. Additionally, the inter-dot coupling of the double quantum dot can be tuned to a large extent according to the voltage on the middle gate. The quantum dot is shown to be tunable from a single dot to a well-isolated double dot. To assess the stability of such design, the potential fluctuation induced by 1/f noise wasmore »« less
