Abstract

original image

The cover illustrates a forest of bicolor porous silicon nanowires with modulated porosity. M. Ferrari et al. report on page 2231 the synthesis of biodegradable porous silicon barcode nanowires with segment-specific morphological, mechanical, and photonic properties by metal-assisted etching. The presented phase diagrams of nanostructures contribute to clarify the competing roles of metal nanoparticles and ions in the formation of various silicon nanostructures, enabling application-specific design.
