Holey germanium

Abstract:
Porous materials can have unusual properties such as large surface areas, making them ideal as catalysts and sensors. Silicon containing nanoscale pores can emit light, even though ordinary silicon cannot. Now two independent groups of researchers in the US have developed techniques to make porous versions of germanium – another semiconductor widely used in microelectronics. The material could be used to make more efficient solar cells and chemical sensors.
