    Notes: We report the results of a systematic investigation of radiative recombination processes of the free-carrier plasma confined in Ga0.47In0.53As/Al0.48In0.52As multiple-quantum-well structures on InP substrate, either undoped or modulation doped. Photoluminescence under low- and high-excitation intensity, luminescence excitation, and optical gain measurements have been used to study the electronic transitions and the optical amplification in the temperature range 10–300 K. Space-resolved luminescence has also been adopted to distinguish between the spontaneous and the stimulated spectral contributions to the observed luminescence collected along different directions with respect to the [001] growth axis of the heterostructures. Optical gain up to 300 K has been observed in the undoped samples under photoexcitation quasiresonant with the confined states in the quantum wells. The theoretical analysis of the optical gain spectra furnishes quantitative data on the electron-hole plasma ground level. In the n-type modulation-doped samples the application of intense optical pumping allows us to observe the transition from the one-component electron plasma to a two-component electron-hole plasma through the rising of a sharp stimulated emission in the optical spectra. Also in this case we observe optical gain up to room temperature.

    Notes: A study has been made of the effect of hydrostatic pressure on an AlAs/GaAs/AlAs resonant tunneling diode in which the electrodes have been deliberately asymmetrically doped. In reverse bias, current is injected into the structure from a highly doped n+-GaAs electrode and in forward bias from a two-dimensional accumulation layer at the GaAs/AlAs interface. When large hydrostatic pressures are applied at 77 K, regions of negative differential resistance are induced in both bias directions. Current maxima with peak-to-valley ratios as large as 4 have been measured at 8 kbar. The intrinsic asymmetry of the structure aids in the identification of the origins of these features in terms of the X-point conduction-band minima of the device.

    Notes: We have performed a series of photoreflectance measurements in a modulation-doped AlGaAs/GaAs heterojunction containing a high mobility two-dimensional electron gas. Measurements were performed as a function of temperature in the range 2 K≤T≤300 K. We studied the Franz–Keldysh oscillations associated with the E0 transition of both the GaAs and AlGaAs. The fields obtained from these oscillations for both sides of the heterojunction are quite different. Also, the temperature dependence of these fields are radically different. In fact, the temperature dependence of the field in the GaAs side of the modulation-doped heterojunction sample is very similar to that of the field in a single undoped GaAs film deposited on a GaAs substrate, where no two-dimensional electron gas is present. This shows that the field producing the observed oscillations on the GaAs side of the modulation-doped heterojunction sample is not related to the field that confines the two-dimensional electron gas.

    Notes: The analysis of the process of establishing a thermal equilibrium in a GaAs sample, in which the metastable state was created by high pressure freeze-out, makes possible a determination of the energy barrier for emission from resonant DX centers. We have found that Si and S centers exhibit qualitatively different pressure behavior. This result casts doubt on some models describing DX center.

    Notes: The direct formation of mesoscopic surface corrugations on high-index GaAs substrates during growth by molecular-beam epitaxy is reported. The accumulation of microscopic steps on GaAs (210) to produce one-dimensional step arrays with a 230 A(ring) lateral periodicity is followed by reflection high-energy electron diffraction. The surprisingly high uniformity of the resulting mesoscopic step array is directly confirmed by atomic force microscopy. The shape of the steps is imaged by high-resolution transmission electron microscopy. Being comparable to the exciton Bohr radius in GaAs this length scale of the lateral periodicity is of particular importance for modulating the electronic properties of GaAs-based heterostructures. Pronounced red shifts in the luminescence of undoped GaAs/AlAs multilayer structures and an enhanced intensity at room temperature are observed. n-type modulation-doped heterostructures exhibit an anisotropic conductivity.

    Notes: We studied the light scattering spectra of three molecular beam epitaxy GaAs samples with Si-δ doping. A broad feature appears in these spectra which is similar to that attributed by other authors to resonant Raman scattering by electronic intersubband transitions. By studying the dependence of this emission on exciting laser photon energy we believe that this line is really produced by nonequilibrium luminescence at the E0+Δ0 gap.
