M08200 - SEMI M82 - Test Method for the Carbon Acceptor Concentration in Semi-Insulating Gallium Arsenide Single Crystals by Infrared Absorption Spectroscopy Revision:SEMI M82-0712 - Superseded The method covers square andThis Test Method covers the determination of the carbon content in GaAs using infrared (IR) absorption. The test method utilizes the linear relationship between the carbon content and the integrated absorption of the localized vibration of substitutionally bonded carbon (CAs). At a measurement temperature of 300 K (room temperature) this absorption band is observed at 580 cm1, at 77 K between 582 and 583 cm1. This Test Method covers the determination
