Combining direct bandgap III-V compound semiconductors, such as InAs and GaAs, with silicon to realize on-chip optical light emitters and detectors at telecommunication wavelengths is an important technological objective. However, traditional thin film epitaxy of InAs and GaAs on silicon is challenging because of the high lattice mismatch between the involved materials. These epitaxial thin films exhibit a poor quality at the interface with silicon, limiting the performance of future devices. Nanowires can overcome the mismatch challenge owing to their small lateral size and high aspect ratio. Thanks to their free, unconstrained surfaces, nanowires release the mismatch strain via elastic lateral relaxation. In this context, my thesis aimed ...
