Reduction of AlGaAs Heterostructure High-Index-Contrast Ridge Waveguide Scattering Loss By Sidewall Smoothing Through Oxygen-Enhanced Wet Thermal Oxidation
We demonstrate the efficacy of oxidation smoothing of sidewall roughness in high-index-contrast AlGaAs heterostructure ridge waveguides via oxygen-enhanced nonselective wet thermal oxidation for reducing scattering loss.

The Effect of Microwave-Frequency Discharge-Activated Oxygen on the Microscale Structure of Low-Temperature Water Ice Films
Low-temperature, amorphous water ice films grown by vapor deposition under high-vacuum are exposed to microwave-frequency discharge-activated oxygen in order to investigate its effect on the ice surface.

Thermochemistry of Gaseous Ammonium Nitrate, NH4NO3(g)
From the measured molecular weight of vapor over NH4NO3(c) by the simultaneous torsion-effusion/mass loss method, the partial pressure of NH4NO3(g) was evaluated over the range 321−360 K; in addition, the…
