Semiconductor nanowires (NW) can solve the problem of inefficient conversion of waste heat to electricity. The large surface-to-volume ratio results in reduced thermal transport due to phonon scattering while the electrical performance can be improve

Recent demonstrations of direct integration of GaAs-based nanowire lasers on Si photonic circuits exhibited efficient in-coupling of lasing emission to proximal waveguides - however, transmission in the Si waveguide suffered from high absorption loss

III-V semiconductor nanowires (NW) are being considered as future coherent light sources for optoelectronic chips due to their small footprint and high refractive index. The 1D confinement also results in a natural Fabry-Perot resonance cavity. Howev

Ultrafast and external quantum efficiency measurements were performed on InAs/InAlAs core-shell nanowires. Rates of different recombination mechanisms were determined, and the carrier densities ranges at which each dominates, an important considerati
