Domain-Engineered Thin-Film LiNbO 3 Pyroelectric-Bicell Optical Detector

August 1, 2001
Author(s)
John H. Lehman, A. M. Radojevic, R M. Osgood
We have fabricated a bicell detector consisting of a single freestanding 10 um thick film of single-crystal lithium niobate (LiNbO3), having two adjacent domains of opposite spontaneous polarization, and hence two adjacent pyroelectric detector regions of

Early Stage Crystallization in Poly (Ethylene-Co-Hexene) by SAXS/WAXD, DSC, OM and AFM

August 1, 2001
Author(s)
G Z. Wang, Haonan Wang, K Shimizu, Charles C. Han, B S. Hsiao
Isothermal crystallization in the early stages of one short-chain branching polyethylene, PEH, is examined by time-resolved SAXS/WAXD, DSC, optical microscope and AFM. WAXD showed a rapid decrease of the inter-chain distance in the amorphous phase at the

Edge Determination for Polycrystalline Silicon Lines on Gate Oxide

August 1, 2001
Author(s)
John S. Villarrubia, Andras Vladar, J R. Lowney, Michael T. Postek
In a scanning electron microscope (SEM) top-down secondary electron image, areas within a few tens of nanometers of the line edges arc characteristically brighter than the rest of the image. In general, the shape of the secondary electron signal within

Electric Force Microscopy with a Single Carbon Nanotube Tip

August 1, 2001
Author(s)
John A. Dagata, F S. Chien, S Gwo, K Morimoto, T Inoue, J Itoh, H Yokoyama
Carbon nanotube tips offer a significant improvement over standard scanned probe microscope (SPM) tips for electrical characterization of nanodevice structures. Carbon nanotube tips are compatible with requirements for integrated SPM probe station

Electrochemical Properties of Nanocrystalline Cadmium Stannate Films

August 1, 2001
Author(s)
Gintaras Valincius, Vytas Reipa, V L. Vilker, John T. Woodward IV, Mark D. Vaudin
Electrochemical properties of the sol-gel nanocrystalline cadmium tin oxide electrodes (CTO) were investigated in 0.2 M potassium chloride buffered at pH 7.4 with phosphate. Films were found to be n-type degenerate semiconductors with charge carrier levels

Electronic Display Metrology--Not a Simple Matter

August 1, 2001
Author(s)
Edward F. Kelley
Most would assume that the characterization of electronic display quality would be a straightforward process offering few complications. However, what the eye sees can be very difficult to capture accurately and quickly in a meaningful way. With the advent

Elimation of Intensity Noise at SURF III

August 1, 2001
Author(s)
Uwe Arp, K Harkay, K Kim, Thomas B. Lucatorto
Most applications of synchrotron radiation are not very sensitive to source intensity fluctuations. Fourier-transform spectroscopy, however, is very sensitive to intensity noise with frequencies of few Hz to several kHz. An infrared spectrometer installed

Fire Alarm Systems With Building Automation and Control Systems

August 1, 2001
Author(s)
Steven T. Bushby
Integrating fire alarm systems with building automation systems can result in many economic and operational benefits. Such integration requires communication standards and careful design practices. BACnet is an internationally recognized communication

Guidelines for the Development of Abstract Test Suites, Edition 2

August 1, 2001
Author(s)
Allison Barnard Feeney
ISO 10303 is an International Standard for the computer-interpretable representation of product data and for exchange of product data. The objective is to provide a neutral mechanism capable of describing product data throughout their life cycle. This

Heat Feedback to the Fuel Surface in Pool Fires (NIST SP 971)

August 1, 2001
Author(s)
Anthony P. Hamins, S. J. Fischer, Takashi Kashiwagi
A series of measurements designed to investigate the heat feedback in pool fires burning liquid fuels are reported. Such measurements are essential for the development and validation of detailed models which predict the burning rate of liquid hydrocarbons

High Throughput Approach to Crystallization in Thin Films of Isotactic Polystyrene

August 1, 2001
Author(s)
Kathryn L. Beers, Jack F. Douglas, Eric J. Amis, Alamgir Karim
The dependence of the crystallization rate of isotactic polystyrene was measured as a function of film thickness and temperature on films with continuous gradients. The results agreed with literature values obtained on discrete films. This validates the
