What is the role of indium arsenide? There's a lot of people who don't know about indium arsenide, and here's the introduction to it:
Indium arsenide is composed of indium and arsenic Ⅲ V compound semiconductor materials.
The normal temperature is silvery solid, has the crystal structure of the flash type, the lattice constant is 0.6058 nm, the density is 5.66 g/cm (solid), 5.90 g/cm (melting point liquid). The band structure is the direct transition, the width of the forbidden band (300K) 0.45 eV. The InAs phase diagram is shown here.
InAs crystal with high electron mobility and migration rate ratio (u e/u h = 70), the magnetic resistance effect of low and small temperature coefficient of resistance, is a manufacturer of magnetic resistance and hall components ideal material. InAs emission wavelength of 3.34 microns In InAs substrate grow In lattice matching - GaAsSb, InAsPSb and InAsSb multiple epitaxial material, can be made 2 ~ 4 mu m band laser and detector of optical fiber communication.
