- Scope
- This standard specifies the principles, instruments and equipment, measurement procedures, result calculation and accuracy of infrared absorption measurement of chromium concentration in semi-insulating gallium arsenide. This standard is applicable to the determination of Cr concentration in semi-insulating gallium arsenide grown by the chromium doping level method, and is suitable for sample thicknesses of 2 to 4 mm. Not suitable for samples with chromium concentration greater than 1.5×10^(17)cm^(-3).
