Self-organized indium arsenide quantum dots for solar cells

Researchers exploit the self-organization of semiconducting nanocrystals by the Stranski-Krasnov (SK) mode of crystal growth for producing ordered, highly dense, and highly uniform quantum dots. This bottom-up approach yields much better results than the conventional photolithographic or top-down methods widely used for the fabrication of nanostructures.
