Journal ArticleDOI
Doping-enhanced radiative efficiency enables lasing in unpassivated GaAs nanowires
Tim Burgess,Dhruv Saxena,Sudha Mokkapati,Zhe Li,Christopher R. Hall,Jeffrey A. Davis,Yuda Wang,Leigh M. Smith,Leigh M. Smith,Lan Fu,Philippe Caroff,Hark Hoe Tan,Chennupati Jagadish +12 more
TL;DR: This work employs controlled impurity doping to increase the rate of radiative recombination and demonstrates lasing from a nanomaterial that combines high radiative efficiency with a picosecond carrier lifetime ready for high speed applications.
Journal ArticleDOI
Light trapping with plasmonic particles: beyond the dipole model.
TL;DR: It is estimated that an optimal array of nanoparticles on a 2 μm Si substrate can provide up to 71% of the enhancement in absorption achievable with an ideal Lambertian rear-reflector, compared to an estimate of 67% for conventional pyramid-type light trapping schemes.
Journal ArticleDOI
Resonant nano-antennas for light trapping in plasmonic solar cells
TL;DR: In this paper, the influence of nanoparticle height on light trapping in thin-film solar cells covered with metal nanoparticles is investigated, and it is shown that in taller nanoparticles the scattering cross-section is enhanced by resonant excitation of plasmonic standing waves.
Journal ArticleDOI
