Nanoscale worlds sometimes resemble macroscale roller-coaster style hills, placed at the tip of a series of hexagons. Surprisingly, these nanohills stem from the self-organization of particles — the very particles that have been eroded and subsequently redeposited following the bombardment of semi-conductors with ion beams. Now, a new theoretical study constitutes the first exhaustive investigation of the redeposition effect on the evolution of the roughening and smoothing of two-dimensional surfaces bombarded by multiple ions.

A new approach for better integrating medical devices with biological systems has been developed by scientists with the first skeleton-like silicon spicules ever prepared via chemical processes.

Microstructures made of adjoining semiconductor disks could lead to powerful nanoscale sensors.

Semiconductor nanocrystals known as quantum dots (QDs) are increasingly being used as photoluminescent materials in bio-imaging, photonics, and optoelectronic applications. However, these QDs must have stable photoluminescence properties to be …
