A photoluminescence study of δ-doped GaAs
Samples of GaAs 8-doped with beryllium have been studied with photoluminescence. With a lightly doped sample, (2 x 1016 Be atoms per m2) a spectral feature is observed which can be interpreted as caused by radiative recombinations between spatially non-confined conductionband electrons and acceptor-related holes forming a miniband system confined spatially to the &doped region. With higher dens...
متن کاملObservation of the quantum Hall effect in δ-doped SrTiO3
The quantum Hall effect is a macroscopic quantum phenomenon in a two-dimensional electron system. The two-dimensional electron system in SrTiO3 has sparked a great deal of interest, mainly because of the strong electron correlation effects expected from the 3d orbitals. Here we report the observation of the quantum Hall effect in a dilute La-doped SrTiO3-two-dimensional electron system, fabrica...
متن کاملA novel model on time-resolved photoluminescence measurements of polar InGaN/GaN multi-quantum-well structures
Based on carrier rate equation, a new model is proposed to explain the non-exponential nature of time-resolved photoluminescence (TRPL) decay curves in the polar InGaN/GaN multi-quantum-well structures. From the study of TRPL curves at different temperatures, it is found that both radiative and non-radiative recombination coefficients vary from low temperature to room temperature. The variation...
متن کاملSpatial Inhomogeneity of Photoluminescence in InGaN Single Quantum Well Structures
Spatial distribution of photoluminescence (PL) spectra has been assessed in an InGaN single quantum well (SQW) structure by means of fluorescence microscopy and scanning near-field optical microscopy (SNOM) under illumination-collection mode. The PL intensity of fluorescence image is uniform at 77 K, but the dark spot areas were extended with increasing temperature. The nearfield PL images reve...
متن کاملAgCl-doped CdSe quantum dots with near-IR photoluminescence
We report the synthesis of colloidal CdSe quantum dots doped with a novel Ag precursor: AgCl. The addition of AgCl causes dramatic changes in the morphology of synthesized nanocrystals from spherical nanoparticles to tetrapods and finally to large ellipsoidal nanoparticles. Ellipsoidal nanoparticles possess an intensive near-IR photoluminescence ranging up to 0.9 eV (ca. 1400 nm). In this artic...
