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

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 ...

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

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 ...

Researchers at Imec have found a way to grow lasers directly on siliconImec’s lasers use gallium arsenide, a material that ...

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 ...

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 ...
