Scope

This standard specifies the infrared absorption test method for carbon concentration in non-doped semi-insulating gallium arsenide wafers. This standard applies to the determination of carbon concentration in non-doped semi-insulating gallium arsenide wafers with a resistivity greater than 1.0×107 Ω·cm. The lowest carbon concentration that can be determined is 4.0×1014 cm-3.
