Analysed Data for Nanoskived GaAsP/GaAs Heterostructures: PL Spectra Fit Parameters, Geometrical Data from SEM, Transition Energies from Nextnano Simulations

Dataset

Description

This dataset is used in the research "Improving Quantum Well Tube Homogeneity Using Strained Nanowire Heterostructures". It underpins the findings that the radial quantum well heterostructure, specifically the GaAsP/GaAs core/shell, configuration is able to host highly strained systems that improve optoelectronic homogeneity with a reduced dependence on overall morphological variations. h5 dataset containing 3 groups of analysed data: Photoluminescence (PL) map fitting data: Lasher-Stern-Wurfel (LSW) fitting parameters, coordinates of individual heterostructures within PL map, raw PL spectra and corresponding LSW fitted curves Data from analysed Scanning Electron Microscopy (SEM) images including diameters, coordinates of individual structures, solidity and eccentricity of detected heterostructures Transitions energies from nextnano simulations for 10 eigenvalues at a series of quantum well (QW) widths, L, from L = 3 to 12 nm at differing phosphorous concentrations (P = 44%, 47% and 50%) in the strained systems and in an unstrained system for comparison. Analysis scripts (MATLAB) are also provided, with a readme.txt file for instructions on how to use and replicate figures from the associated manuscript.
