We report a single broadband on-wafer resistance calibration standard fabricated with a 15-nm-thick gold resistor on an alumina substrate. Because the resistor film is much smaller than the skin depth at microwave frequencies, this proposed standard

A new statistical approach for modeling diffraction profiles is introduced, using Bayesian inference and a Markov chain Monte Carlo (MCMC) algorithm. This method is demonstrated by modeling the degenerate reflections during application of an electric

Alkali-free glasses, which exhibit high energy storage densities ( $\sim 35$ J/cc), present a unique opportunity to couple high temperature stability with high breakdown strength, and thus provide an avenue for capacitor applications with stringent t

Ferroelastic domain walls in ferroelectric materials possess two properties that are known to affect phonon transport: a change in crystallographic orientation and a lattice strain. Changing populations and spacing of nanoscale-spaced ferroelastic do
