TL;DR: In photoluminescence (PL) spectra of a ZnS-ZnTe superlattice grown on GaAs substrate, a multi-band structure with equal energy spacing of about 90meV has been observed as discussed by the authors.

TL;DR: In this article, the electric field dependence of the electroreflectance intensities and that of the photocurrent ones was investigated by systematically measuring the electro reflectance and photocurrent spectra at 77 K.

TL;DR: In this article, the superlattice of the rare-earth metals was grown by means of reactive evaporation (RE) with flection high-energy electron diffraction (RHEED) intensity oscillations.
Abstract: Perfect unit cell-by-unit cell growth of RBa 2 Cu 3 O 7−δ (R; rare-earth metals) was first demonstrated by means of X-ray diffraction. The superlattice of [(YBa 2 Cu 3 O 7−δ ) 1 /(PrBa 2 Cu 3 O 7−δ ) 1 ] 10 was grown by means of reactive evaporation (RE) with flection high-energy electron diffraction (RHEED) intensity oscillations. No aperiodicity and no intermixing of YBa 2 Cu 3 O 7−δ and PrBa 2 Cu 3 O 7−δ due to the interfacial roughness were found, indicating that the RE-growth monitored in situ by RHEED oscillations makes the exact unit cell growth following the two-dimensional growth manner.
