Fractional Quantum Hall States in a Ge Quantum Well
O. A. Mironov, N. d'Ambrumenil, A. Dobbie +3
Measurements of the Hall and dissipative conductivity of a strained Ge quantum well on a SiGe/(001)Si substrate in the quantum Hall regime are reported. We find quantum Hall states…
Magnetoresistivity in a Tilted Magnetic Field in p-Si/SiGe/Si Heterostructures with an Anisotropic g-Factor: Part II
I. L. Drichko, I. Yu. Smirnov, A. V. Suslov +2
The magnetoresistance components and were measured in two p-Si/SiGe/Si quantum wells that have an anisotropic g-factor in a tilted magnetic field as a function of…
Acoustic Studies of AC Conductivity Mechanisms in -GaAs/AlGaAs in the Integer and Fractional Quantum Hall Effect Regime
I. L. Drichko, I. Yu. Smirnov, A. V. Suslov +1
In case of a of the heterostructure n-GaAs/AlGaAs with sheet density cm and mobility cm/Vs with integer and fractiona…
Large Magnetoresistance of a Dilute -Si/SiGe/Si Quantum Well in a Parallel Magnetic Field
I. L. Drichko, I. Yu. Smirnov, A. V. Suslov +2
We report the results of an experimental study of the magnetoresistance in two samples of -Si/SiGe/Si with low carrier concentrations =8.2 cm a…
Searches for Skyrmions in the Limit of Zero g-Factor
D. R. Leadley, R. J. Nicholas, D. K. Maude +4
Energy gaps have been measured for the ferromagnetic quantum Hall effect states at v=1 and 3 in GaAs/GaAlAs heterojunctions as a function of Zeeman energy, which is reduced to zero…
Critical Collapse of the Exchange Enhanced Spin Splitting in 2-D Systems
D. R. Leadley, R. J. Nicholas, J. J. Harris +1
The critical filling factor v_c where Shubnikov-de Haas oscillations become spin split is investigated for a set of GaAs-GaAlAs heterojunctions. Finite temperature magnetoresistanc…
