Prospects for nanowire sculptured-thin-film devices

Abstract

In this paper, we introduce a modified serial bideposition (SBD) method, asymmetric SBD, for depositing sculptured thin films (STFs) which may allow added control of the surface area, void accessibility, and optical properties of STFs. Results on using TiO2 STFs with spectral-hole filters as vapor/liquid sensors are presented. In addition, solar cell, microcavity, biological sensing, and bioabsorption devices utilizing STFs are discussed.
