A prison for photons in a diamond-like photonic crystal

A novel type of reso­nant cavity serves as a prison for photons. The cavity confines light in all three dimensions in space inside a photonic crystal. The crystals have a struc­ture similar to how atoms are arranged in diamond gems.

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.

2-D materials' crystalline defects key to new properties

Understanding how atoms 'glide' and 'climb' on the surface of 2-D crystals like tungsten disulphide may pave the way for researchers to develop materials with unusual or unique characteristics, according to an international team of researchers.
