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 ...

Many next-generation quantum devices rely on single-photon emitters based on optically active defects in solids, known as ...

Silicon photonics uses light to transmit data instead of relying on electrical signals, but since silicon itself can’t ...

The tube furnace proved itself up to the task by creating a thin layer of silicon dioxide on a scrap of silicon wafer. In the current work, [ProjectsInFlight] takes that initial success and builds ...

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 ...

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 ...

It is employed for depositing photoresists, dielectric layers (e.g., silicon dioxide, silicon nitride), and conductive polymers (e.g., PEDOT:PSS) onto silicon wafers or other substrates. The precise ...

Scientists have developed a safety evaluation technology for nanoparticles used in UV-blocking cosmetics and listed it as an ...

The Korea Research Institute of Standards and Science (KRISS) has developed a safety evaluation technology for nanoparticles* used in UV-blocking cosmetics and has listed it as an international ...

Phosphorus trifluoride acted as a nitrous boost for silicon dioxide etching, quadrupling the rate. They also tested ammonium fluorosilicate. The team detailed its findings in a study published in ...
