Abstract
US nano-structures were produced electrochemically using porous silicon (PS ) as a template/substrate. AFM and SEM images show that the US deposit are grains of similar to 100 nm, each of which is an aggregate of smaller parti cles of several nanometers. XANES studies of the US nano-structures togethe r with bulk US were conducted. The electronic behavior and optical properti es of the CdS/PS composite, particularly those relevant to nano-size effect s, were discussed. (C) 2001 Elsevier Science BY All rights reserved.
