Mapping the spatial distribution of charge carriers in quantum-confined heterostructures
Quantum-confined nanostructures are considered 'artificial atoms' because the wavefunctions of their charge carriers resemble those of atomic orbitals. For multiple-domain heterostructures, however, carrier wavefunctions are more complex and still not well understood. We have prepared a unique series of cation-exchanged Hg(x)Cd(1-x)Te quantum dots (QDs) and seven epitaxial core-shell QDs and me...
متن کاملDensity and spatial distribution of charge carriers in the intrinsic n-type LaAlO3-SrTiO3 interface
In order to establish the density and spatial distribution of charge carriers intrinsic to the n-type LaAlO3-SrTiO3 heterointerface, we carry out first-principles calculations on the LaAlO3 n SrTiO3 15 slab model with n=2–10. As the thickness of the LaAlO3 layer increases, the charge transfer from LaAlO3 to SrTiO3 converges to half an electron per two-dimensional unit cell. It is found that the...
متن کاملEvaluation and Mapping Spatial Distribution of Copper Pollution in Soil and Water of Vineyard Garden
Background and objectives: The use of copper based fungicides is a crucial part of agricultural operations in vineyards, increasing productivity and crops. However, the long term application of fungicide could increase the copper concentration in the vineyard soils. Methods: In this study, soil and water chemical parameters including copper contamination, pH and EC as well as soil organic ...
متن کاملRecombination of charge carriers in heterostructures with Ge nanoislands grown on Si(100)
In this paper, the study of the recombination of non-equilibrium charge carriers and determination of recombination mechanisms in Ge/Si heterostructures with nanoislands have been presented. The effects of long-term photoconductivity decay in Ge/Si heterostructures with Ge nanoislands have been found as caused by variations of the electrostatic potential in the near-surface region of Si(100) su...
