1. Resonant Soft X-Ray Photofragmentation of Propane
William E Wallace III, Daniel A Fischer
A comparison was made between the mass spectra of propane (CH6d3^CH^d2^CH^d3^) for resonant soft X-ray photofragmentation and electron-impact ionization. The soft X-ray photon energy was tuned to 287.7 eV to promote Auger relaxations from the C-H bo ...
2. X-Ray Absorption Spectroscopy to Probe Interfacial Issues in Photolithography
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Daniel A Fischer, S Sambasivan, Eric K Lin, Ronald Leland Jones, Christopher L Soles, Wen-Li Wu, D L Goldfarb, M Angelopoulos
Control of the shape, critical dimension (CD), and roughness is critical for the fabrication of sub 100 nm features, where the CD and roughness budget are approaching the molecular dimension of the resist polymers1. Here we utilize near edge X-ray a ...
3. A Direct Comparison of Surface and Bulk Chain-Relaxation in Polystyrene
Wen-Li Wu, S Sambasivan, C M Wang, William E Wallace III, Jan Genzer, Daniel A Fischer
Near-edge x-ray absorption fine structure (NEXAFS) spectroscopy was used to meausre simultaneously the relaxation rates of polystyrene (PS) molecules at the free surface and in the bulk. The samples were uniaxially stretched and annealed at temperatu ...
4. A Study of the Packing Density and Molecular Orientation of Bimolecular Self-Assembled Monolayers of Aromatic and Aliphatic Organosilanes on Silica
M B Smith, K Efimenko, Daniel A Fischer, S E Lappi, P E Kilpatrick, Jan Genzer
Bimolecular self-assembled monolayers (SAMs) of aromatic and aliphatic chlorosilanes were self-assembled onto silica and their characteristics were established by contact angle measurement, near-edge X-ray adsorption fine structure spectroscopy, and ...

Abstracts relating to research and development in the NIST Materials Science and Engineering Laboratory (MSEL) are presented for a poster session to be presented to the 2001 MSEL Assessment Panel.
6. Accounting for Auger Yield Energy Loss for Improved Determination of Molecular Orientation Using Soft X-Ray Absorption Spectroscopy
Jan Genzer, E K Kramer, Daniel A Fischer
Partial (Auger) yield near edge X-ray absorption fine structure (NEXAFS) is a structural analytical technique that has been primarily used to measure thespatial orientation and chemical bonding of small molecules on solid (i.e., inorganic or semicond ...
7. An X-Ray Absorption Study of Stoichiometry and Bonding in the Maagnetocaloric Antiperovskite Mn^d3^GaC
L H Lewis, D Yoder, A R Moodenbaugh, Daniel A Fischer, M-H Yu
The effects of carbon content were studied with magnetic and spectroscopic techniques in the imtermetallic perovskite compounds Mn3GaC, Mn3GaC0.90, and Mn3GaC0.78. Mn3GaC undergoes a first order magnetic transition near 160 K which is associated wit ...
8. Anti-Biofouling Properties of Comb-Like Block Copolymer With Amphiphilic Side-Chains
Sitaraman Krishnan, R Ayothi, A Hexemer, J Finlay, K E Sohn, R Perry, Christopher K. Ober, E J Kramer, M E Callow, J A Callow, Daniel A Fischer
Surfaces of novel block copolymers with amphiphilic side chains were studied for adhesion of marine organisms. the surface-active polymer, obtained by grafting fluorinated molecules with hydrophobic and hydrophilic blocks to a block copolymer precurs ...

10. Asphaltene Adsorption onto Self-Assembled Monolayers
of Mixed Aromatic and Aliphatic Trichlorosilanes
Daniel A Fischer, Saloman Turgman-Cohen, Mathew Smith, P K Kilpatrick, Jan Genzer
The adsorption of asphaltenes onto flat solid surfaces modified with mixed self-assembled
monolayers (SAMs) of aliphatic and aromatic trichlorosilanes with varying wettabilities,
aromaticities, and thicknesses is tested. The mixed SAMs are characte ...
