21. Nonlinear Modeling of Tunnel Diode Detectors
Published: 9/24/2004
Authors: David K Walker, Kevin J Coakley, Jolene D Splett
Abstract: We investigate the sensitivity and nonlinear properties of a tunnel diode microwave detector as functions of the input power and the load impedance presented at the detector's output. We compare the two-tone method estimate of nonlinearity with preci ...

22. Measuring residual resistivity ratio of high-purity Nb
Published: 7/27/2004
Authors: Loren F Goodrich, Theodore C Stauffer, Jolene D Splett, Dominic Frank Vecchia
Abstract: We compared methods of measuring the residual resistivity ratio (RRR) of high-purity Nb using transport current. Our experimental study is intended to answer some fundamental questions about the best measurement for RRR and the biases that may exist ...

23. Estimation of Q-Factors and Resonant Frequencies
Published: 3/1/2003
Authors: Kevin J Coakley, Jolene D Splett, Michael D Janezic, R F Kaiser
Abstract: We estimate the quality factor Q and resonant frequency f^do^ of a microwave cavity based on resonance curve observations on an equally-spaced frequency grid. The observed resonance curve is the squared magnitude of an observed complex scattering pa ...

24. Estimation of Q-factors and Resonant Factors
Published: 3/1/2003
Authors: Kevin J Coakley, Jolene D Splett, Michael D Janezic, Raian K. Kaiser
Abstract: We estimate the quality factor Q and resonant frequency f^d0^ of a microwave cavity based on resonance curve observations on an equally-spaced frequency grid. The observed resonance curve is the squared magnitude of an observed complex scattering par ...

25. Accuracy of AlGaAs Growth Rates and Composition Determination Using RHEED Oscillations
Published: 1/1/2003
Authors: Todd E Harvey, Kristine A Bertness, Robert K. Hickernell, C. M. Wang, Jolene D Splett
Abstract: We investigate the sources of uncertainty in the measurement of the reflection high-energy electron diffraction (RHEED) intensity oscillations during growth of AlAs, GaAs, and AlGaAs on GaAs substrates, and the resulting effects on predicted growth r ...

26. Accuracy of AlGaAs Rates and Composition Determination Using RHEED Oscillations
Published: 9/1/2002
Authors: Todd E Harvey, Kristine A Bertness, Chih-Ming Wang, Jolene D Splett
Abstract: Reflection high-energy electron diffraction (RHEED) oscillations are widely used in molecular beam epitaxy (MBE) as a technique to calibrate material growth rates. The growth rates are used to predict the composition of the following growth run. For ...

28. NIST Measurement Services: Measurement Assurance Program for the Spectral Density of Relative Intensity Noise of Optical Fiber Sources Near 1550 nm
Series: Special Publication (NIST SP)
Report Number: 250-57
Published: 9/1/2000
Authors: Gregory E. Obarski, Jolene D Splett
Abstract: This paper provides the documentation to establish a measurement assurance program (MAP) for the spectral density of relative intensity noise (RIN) of optical sources. A standard is made available to industry for high-precision calibration of RIN me ...
