But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main constituent of silicate minerals such as sand, quartzite or granite — elemental silicon itself is ...

Researchers from EPFL and IBM have developed a groundbreaking photonic-chip-based traveling-wave parametric amplifier (TWPA) ...

A trio of astronomers from the University of Tokyo and Niigata University have found what they describe as "peculiar embedded icy objects" thousands of light years from Earth. Takashi Shimonishi ...

Using gallium phosphide-on-silicon dioxide technology, thecompact photonic chip boosts signals with unprecedented efficiency.

This is then coated with a layer of silicon dioxide -- kind of a silicon rust, which doesn't conduct electricity. On top of this is placed a chemical called photoresist. Flashing a pattern of ...

Australia’s only silicon manufacturer has been awarded funding from the Albanese Labor government, to help decarbonise its operations.

Thin films can be made from a variety of materials, including metals (e.g., gold, silver), oxides (e.g., silicon dioxide, titanium dioxide), and semiconductors (e.g., silicon, gallium arsenide). These ...

The trick was to accept the lattice mismatch and instead focus on confining the resulting flaws through a layer of silicon dioxide on top of the wafer. In this layer trenches are created (see top ...

To achieve this goal, ISK uses surface-treatment technology to coat titanium dioxide with thin layers of other oxides, including silicon, aluminum and zinc oxides. “We can easily modify pigment ...

They begin by covering a silicon wafer with a layer of silicon dioxide and etching in arrowhead-shaped trenches (“like a field plowed prior to planting” as IEEE Spectrum describes it).

The world's demand for alternative fuels and sustainable chemical products has prompted many scientists to look in the same direction for answers: converting carbon dioxide (CO 2) into carbon monoxide ...
