About (7N5) 99.999995% Arsenic Metal

Ultra high purity (7N5, 99.99995%) Arsenic ingots, chunks, and rods are employed as precursor materials for the epitaxial growth of single crystal III/V semiconductor thin films and nanoparticles via molecular beam epitaxy (MBE) and other techniques. These compound semiconductors are critical to the optoelectronics industry and include gallium arsenide (GaAs), indium arsenide (InAs), and indium gallium arsenide (InGaAs). Applications include high frequency integrated circuits and optoelectronic devices such as photodetectors, transistors, light emitting-diodes (LEDs), laser diodes, and photovoltaic solar cells. American Elements' rigorous standards ensure the absolute minimum levels of chemical impurities including oxygen and other gases. Standard and custom sizes are available, as are other purities including 7N and 6N (see arsenic ingots for more information).

The number of electrons in each of arsenic's shells is 2, 8, 18, 5 and its electron configuration is [Ar] 3d¹⁰ 4s² 4p³. The arsenic atom has a radius of 119 pm and a Van der Waals radius of 185 pm. Arsenic was discovered in the early Bronze Age, circa 2500 BC. It was first isolated by Albertus Magnus in 1250 AD. In its elemental form, arsenic is a metallic grey, brittle, crystalline, semimetallic solid. Arsenic is found in numerous minerals including arsenolite (As₂O₃), arsenopyrite (FeAsS), loellingite (FeAs₂), orpiment (As₂S₃), and realgar (As₄S₄). Arsenic has numerous applications as a semiconductor and other electronic applications as indium arsenide, silicon arsenide and tin arsenide. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors.
