“…MP resonances of a 2DEG have been studied by far-infrared and microwave (mw) transmission spectroscopy of small mesa arrays, 3 Hall bars and quantum dots, 4,5 as well as of a single 2DEG disk. 6 MP's were also studied by optically detected resonance utilizing the heating of 2D-electrons by mw radiation in order to modulate the photoluminescence (PL) spectrum. The PL modulation is resonantly enhanced at the magnetoplasmon resonances, thus providing a sensitive detection of confined 2DEG-magnetoplasmons that are excited in 2D-disks, rings and stripes of various sizes.…”

“…Therefore, one or three energy states are possible (Fig. 2), allowing for hysteretic effects [53,54,55,56], which also have quantum analogies in solid-state physics [57,58,59].…”

A classical particle oscillating in an arbitrary high-frequency or static field effectively exhibits a modified rest mass m eff derived from the particle averaged Lagrangian. Relativistic ponderomotive and diamagnetic forces, as well as magnetic drifts, are obtained from the m eff dependence on the guiding center location and velocity. The effective mass is not necessarily positive and can result in backward acceleration when an additional perturbation force is applied. As an example, adiabatic dynamics with m|| > 0 and m|| < 0 is demonstrated for a wave-driven particle along a dc magnetic field, m|| being the effective longitudinal mass derived from m eff . Multiple energy states are realized in this case, yielding up to three branches of m|| for a given magnetic moment and parallel velocity.

“…However, simultaneous irradiation with radio frequencies which would excite NMR of Ga, As or In did not influence the hysteresis effects, showing that Overhauser effects were not causing the experimental observations. Similar hysteresis effects have been described to appear in the microwave absorption and the photoluminescence when cyclotron resonance is excited in 2DEGs, although on much shorter time scales, and have been linked to charge trapping in the heterostructure [57,58]. Slow thermal emission of charges from these unidentified trap states at the low temperatures used for the experiments can easily account for the time constants observed.…”

The results obtained on spin-dependent processes via electrically detected magnetic resonance (EDMR), capacitance-detected magnetic resonance (CDMR) and noise-detected magnetic resonance (NDMR) in a variety of different semiconductor materials, devices and nanostructures are reviewed. Similar to optically detected magnetic resonance (ODMR), these detection methods are significantly more sensitive for the detection of paramagnetic states and defects than conventional electron spin resonance (ESR) and can be applied also to semiconductors with an indirect band gap. Using GaAs/AlGaAs-heterostructures and thin films of amorphous hydrogenated silicon (a-Si:H) as examples, the physics of spin-dependent recombination and its detection via spin-dependent photoconductivity is briefly recapitulated. EDMR on pn-diodes from GaP, GaAsP and group-III nitrides, resonant spin-spin scattering in strained Si/SiGe heterostructures, new hysteresis effects in the longitudinal magneto-transport through two-dimensional electron gases and edge-magneto plasmons in different III-V heterostructures are discussed. Various aspects of ferromagnetic III-V semiconductors are investigated, including doping of GaN with Mn, inhomogeneous magnetization of GaMnAs and control of ferromagnetism in semiconductors via hydrogen. Finally, preliminary EDMR experiments on the detection of single paramagnetic defects in MOSFETs via random telegraph noise are presented.
