Scientists obtain a hexagonal modification of silicon

A team of scientists from Lobachevsky University (Nizhny Novgorod, Russia) has obtained a material with a new structure for applications in next-generation optoelectronics and photonics. This material is one of the hexagonal ...

A revolution in light at the small scale

Light behaves in rather tame and predictable ways when interacting with everyday objects—it travels in straight lines, rebounds when it hits shiny surfaces, and gets bent by lenses. But weird and wonderful things start ...

Ripple patterns in silicon can enhance solar cell efficiency

A*STAR scientists have produced a uniform nanoscale ripple pattern over a wide area on a silicon surface by scanning a femtosecond laser beam across it. Given that a rippled surface is much less reflective than a smooth surface, ...
