Mapping the directional emission of quasi-two-dimensional photonic crystals of semiconductor nanowires using Fourier microscopy
Yannik Fontana, Grzegorz Grzela, Erik P. A. M. Bakkers +1
Controlling the dispersion and directionality of the emission of nanosources is one of the major goals of nanophotonics research. This control will allow the development of highly…
Polarization-dependent light extinction in ensembles of polydisperse, vertical semiconductor nanowires: A Mie scattering effective medium
Grzegorz Grzela, Djamila Hourlier, Jaime Gómez Rivas
We present an experimental and theoretical study of the angle- and polarization-dependent light extinction in random arrays of polydisperse semiconductor nanowires epitaxially grow…
Broadband and omnidirectional anti-reflection layer for III/V multi-junction solar cells
Silke L. Diedenhofen, Grzegorz Grzela, Erik Haverkamp +3
We report a novel graded refractive index antireflection coating for III/V quadruple solar cells based on bottom-up grown tapered GaP nanowires. We have calculated the photocurrent…
