TL;DR: In this article, the authors report on complementary measurements made on a single interface by observing the energy relaxation of carriers by phonon emission, and correlate the phonon emissions observed with changes in the mobility (μ) as a function of electric field (E).

TL;DR: In this article, the spontaneous decay threshold energy for high-frequency phonon propagation in He II at saturated vapor pressure at T = 0.1 K was measured using superconducting tin tunnel generators and aluminum tunnel detectors.

TL;DR: In this paper, a method for the management of nuclear spin immersed in a confined quantum Hall electronic system is proposed, which is characterized by: (a) the application of the Overhauser effect for dynamic nuclear polarization, (b) spin measurement using electrical resistance detection techniques, (c) spin control with microwave/radio frequency methods, and (d) the utilization of the electronic spin exciton as a possible mobile spin transfer mechanism for the eventual realization of a logic gate.

TL;DR: By integrating a p-i-n photodiode photodetector directly into a ballistic electron emission luminescence (BEEL) heterostructure with GaAs quantum-well active region, this paper obtained a photon detection efficiency of more than 10%.

TL;DR: In this paper, the energy transport of near zone edge transverse phonon pulses generated in the process of non-radiative electronhole pair recombination at T = 1.4 K in GaAs and InP was investigated.
