311. Mechanically Robust Spin-On Organosilicates Glasses for Nanoporous Applications
Topic: Materials Science
Published: 2/7/2007
Authors: Hyun Wook Ro, K Char, Eun-Chae Jeon, H C Kim, Dongil Kwon, Hae-Jeong Lee, J. H. Lee, Hee-Woo Rhee, Christopher L Soles, Do Y. Yoon
Abstract: An increasing number of technologies demand nanoporous materials with vastly improved physical, mechanical and thermal properties. This manuscript develops the microstructural basis for synthesizing organosilicate glasses (OSGs) with unprecedented ...

315. In Situ Characterization of Gas-Phase Species Present During Hafnium Oxide Atomic Layer Deposition
Topic: Materials Science
Published: 1/1/2007
Authors: James E Maslar, Wilbur S. Hurst, Donald R Burgess Jr, William Andrew Kimes, Nhan V Nguyen
Abstract: In this work, the species present in the gas phase during atomic layer deposition of hafnium oxide were investigated in an attempt to gain insight into the chemistry of this system. Hafnium oxide was deposited on a silicon substrate using tetrakis(e ...

318. Recommended Practice Guide: DTA and Heat-Flux DSC Measurements of Alloy Melting and Freezing
Series: Special Publication (NIST SP)
Report Number: 960-15
Topic: Materials Science
Published: 11/1/2006
Authors: William J Boettinger, Ursula R Kattner, Kil Won Moon, John Perepezko
Abstract: This document is focused on differential thermal analysis (DTA) and heat-flux differential scanning calorimetry (HF-DSC) of metals and alloys. A thermal analysis guide focused only on metals and alloys is appropriate because they behave quite differ ...
