Optomechanical cavities based on epitaxial GaP on nominally (001)-oriented Si
Paula Mouriño, Laura Mercadé, Miguel Sinusía Lozano +8
Gallium phosphide (GaP) has recently received considerable attention as a suitable material for building photonic integrated circuits due to its remarkable optical and piezoelectri…
Impact of the III-V/Ge nucleation routine on the performance of high efficiency multijunction solar cells
Laura Barrutia, Ivan García, Enrique Barrigon +3
This paper addresses the influence of III-V nucleation routines on Ge substrates for the growth of high efficiency multijunction solar cells. Three exemplary nucleation routines wi…
Hot-Carrier Separation in Heterostructure Nanowires observed by Electron-Beam Induced Current
Jonatan Fast, Enrique Barrigon, Mukesh Kumar +7
The separation of hot carriers in semiconductors is of interest for applications such as thermovoltaic photodetection and third-generation photovoltaics. Semiconductor nanowires of…
Three-dimensional imaging of beam-induced biasing of InP/GaInP tunnel diodes
Cristina Cordoba, Xulu Zeng, Daniel Wolf +4
Electron Holographic Tomography was used to obtain 3-dimensional reconstructions of the morphology and electrostatic potential gradient of axial GaInP/InP nanowire tunnel diodes. C…
Combined photo- and electroreflectance of multijunction solar cells enabled by subcell electric coupling
D. Fuertes Marrón, E. Barrigón, M. Ochoa +1
Electric coupling between subcells of a monolithically grown multijunction solar cell in short circuit allows their simultaneous and independent characterization by means of photo-…
InP/InAsP Nanowire-based Spatially Separate Absorption and Multiplication Avalanche Photodetectors
Vishal Jain, Magnus Heurlin, Enrique Barrigon +11
Avalanche photodetectors (APDs) are key components in optical communication systems due to their increased photocurrent gain and short response time as compared to conventional pho…
