Laser induced sponge-like Si in Si-rich oxides for photovoltaics
(Optical Society of American (OSA), 2013)We show that a sponge-like structure of interconnected Si nanowires embedded in a dielectric matrix can be obtained by laser annealing of silicon rich oxides (SRO). Due to quantum confinement, the large bandgap displayed ...
