The present work gives an overview of the developments in surface-enhanced Raman scattering (SERS) with metal-coated porous silicon used as an active substrate. We focused …
Low-dimensional semiconductor structures, often referred to as nanocrystals or quantum dots, exhibit fascinating behavior and have a multitude of potential applications, especially …
This book presents an overview of the current understanding of the physics of zero- dimensional semiconductors. It concentrates mainly on quantum dots of wide-gap …
Electronic properties of (100),(110), and (111) oriented H‐terminated silicon quantum‐size wires have been calculated within the self‐consistent LCAO method. The quantum …
Porous silicon doped by erbium electrodeposition or from spin-on silica gel film followed by rapid thermal processing at 950° C or higher exhibited liquid-nitrogen and room …
