We report a study of the quantum Hall effect and Shubnikov-dc Haas oscillations in semimctallic type II heterostructures of the strained layer system InAs/Ga1−xInxSb which are almost intrinsic. In high magnetic fields up to 50 T, ρxy has large pea

We have performed a magnetotransport study in both perpendicular and parallel magnetic fields for gated InAs/GaSb double heterostructures. These measurements provide a further proof for the existence of a minigap at the anti-crossing point between th

We report here on the optimization of the growth by atmospheric pressure MOVPE of double heterojunctions and superlattices of GaSb/InAs on both [111]A and [111]B GaAs substrates. The layers were not intentionally doped. Various indium precursors were

Magnetotransport and optical measurements have been carried out on (001) and piezoelectrically active (111) InGaSb/GaSb and InAs/GaSb structures. In accordance with theory, these comparative studies reveal enhanced carrier density and mobility for gr

The quantum Hall effect in InAs/GaSb heterojunctions at very high fields and low temperatures when both the electrons and holes contribute to the quantized Hall conductance was studied. InAs/GaSb were grown by metal organic vapor phase epitaxy and ar

HTS based leads have established themselves for high current carrying applications. This work revisits the issues for commercial magnets with a view to minimizing heat load and space for both the resistive and HTS parts. The paper describes the exper

In circumstances where it is not possible to make perfectly persistent joints, it is not necessary to rework all the joints as a simple flux pump injector could be built with the magnet to stabilize the decay. This is particularly important in the ca

We present a theoretical study of intersubband transitions (IST) in InAs/GaSb superlattices in the presence of a parallel magnetic field. Starting from a model describing a single electron in a single quantum well and extending it to include many-bod

We report parallel magnetic-field-activated intersubband absorption in InAs/GaSb semimetallic superlattices. The samples were studied in the Voigt configuration enabling normal-incidence excitation of the intersubband transition. For samples with nar
