Here we theoretically and experimentally demonstrate that through a careful design optimization, and despite very high dislocation densities (>108cm−2), ultra-thin (∼1 micron) dual junction solar cells with practical efficiencies in excess of 23%

Here we demonstrate the possibility of the fabrication of high/aspect ratio self-assembled dots that nucleate directly on (Al)GaAs spacers away from their wetting layers. We have carefully monitored the strain anisotropies, their evolution and onsets

The ability to control their shape and size and reproducibility of epitaxial quantum dots is considered as key to the performance of many advanced photovoltaic devices. We demonstrated the possibility of extracting real time using reflection high ene

Within the context of the archetype InAs/GaAs self assembled quantum dot system, we provide an in situ, methodology based on the analysis of reflection high energy electron diffraction (RHEED) patterns and demonstrate its ability for real time and si
