New material acts as an efficient frequency multiplier

Higher frequencies mean faster data transfer and more powerful processors—the formula that has been driving the IT industry for years. Technically, however, it is anything but easy to keep increasing clock rates and radio ...

Light-emitting silicon for photonic computing

If computers transmitted data using photons instead of electrons, they would perform better and use less power. European researchers are now studying a new light-emitting alloy of silicon and germanium to obtain photonic ...

Physicists trap light in nanoresonators for record time

An international team of researchers from ITMO University, the Australian National University, and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers ...

Small currents for big gains in spintronics

University of Tokyo researchers have created an electronic component that demonstrates functions and abilities important to future generations of computational logic and memory devices. It is between one and two orders of ...

New robust device may scale up quantum tech, researchers say

Researchers have been trying for many years to build a quantum computer that industry could scale up, but the building blocks of quantum computing, qubits, still aren't robust enough to handle the noisy environment of what ...

Arsenide is an arsenic anion with the charge −3. The trianion is formed by the reduction of arsenic by three electrons. For example heating arsenic powder with excess sodium gives sodium arsenide (Na3As). The anions have no existence in solution since they are extremely basic. These solid salts have very high lattice energies.

An arsenide (compound) is a compound with arsenic in oxidation state −3, but the term is used loosely. The mineral sperrylite (PtAs2) is called a platinum arsenide, but the formal oxidation state for arsenic is −2. because the solid is usually described as Pt4+,As24-. The description of gallium arsenide (GaAs) is more straightforward since it features isolated arsenic centers.

Arsenides are toxic because of the inherent toxicity of arsenic and all of its compounds.

Metal arsenides react with acids to form highly toxic arsine gas.
