Abstract :
Time-resolved terahertz spectroscopic studies were carried out on bulk InP to measure photoconductivity on the picosecond timescale. Comparison of the carrier multiplication quantum yields obtained with those of colloidal InP nanoparticles clearly demonstrate the potential benefit of InP nanoparticle-based next-generation solar cells.
