Lead oxide ceramic makes excellent high-temperature lubricant [PDF]

open access: yes, 1964
A dry lubricant coating in ceramic form consisting of 95 percent lead monoxide and 5 percent silicon dioxide withstood a temperature of 1200 deg F, with a bearing operating at various atmospheric pressures.

Plasmonic Enhancement of Emission from Si-nanocrystals

open access: yes, 2008
Plasmonic gratings of different periodicities are fabricated on top of Silicon nanocrystals embedded in Silicon Dioxide. Purcell enhancements of up to 2 were observed, which matches the value from simulations.

Mass Spectrometric Investigation of the Influence of Water Vapour and Oxygen on Gas‐Phase Reactions of Aluminium Acetylacetonate

open access: yesAdvanced Materials Interfaces, EarlyView.
The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.

Parametrization of the radiation induced leakage current increase of NMOS transistors

open access: yes, 2016
The increase of the leakage current of NMOS transistors during exposure to ionizing radiation is known and well studied. Radiation hardness by design techniques have been developed to mitigate this effect and have been successfully used.

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors

open access: yesAdvanced Materials Interfaces, EarlyView.
The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.

Atomic-scale disproportionation in amorphous silicon monoxide

open access: yesNature Communications, 2016
Amorphous silicon monoxide is known to undergo disproportionation to silicon- and silicon dioxide-like regions, however direct observation of the atomic-scale heterogeneity is still missing.

Technique for depositing silicon dioxide on indium arsenide improves adhesion [PDF]

open access: yes, 1970
Planar array processing of indium arsenide wafers includes dicing into a prescribed geometry, then cleaning and drying, and finally pre-oxidizing in an oxygen atmosphere at 500 degrees C.

Photoluminescence from silicon dioxide photonic crystal cavities with embedded silicon nanocrystals

open access: yes, 2010
One dimensional nanobeam photonic crystal cavities are fabricated in silicon dioxide with silicon nanocrystals. Quality factors of over 9 x 10^3 are found in experiment, matching theoretical predictions, with mode volumes of 1.5(lambda/n)^3 ...
