What is InAs wafer?

 

Indium arsenide is a kind of III-V compound semiconductor material composed of indium and arsenic.It is a silver gray solid with a sphalerite crystal structure at room temperature. The lattice constant is 0.6058nm, and the density is 5.66g/cm (solid) and 5.90g/cm (liquid at melting point). The band structure is a direct transition with a band gap (300K) of 0.45ev. the dissociation pressure of as is only 0.033mpa, and the single crystal can be grown from the melt at atmospheric pressure. The commonly used methods are Hb and LEC. InAs is a kind of semiconductor material which is difficult to purify. The residual carrier concentration is higher than l × 10 / cm, the room temperature electron mobility is 3.3 × 10 ^ 3cm / (V · s), and the hole mobility is 460cm / (V · s). The effective segregation coefficient of sulfur in In and As is close to 1, so it is used as n-type dopant to improve the uniformity of longitudinal carrier concentration distribution. For industrial InAs (s) single crystal, n ≥ 1 × 10 / cm3, μ ≤ 2.0 × 10cm / (V · s), EPD ≤ 5 × 10 / cm3.
