Abstract


The purpose of this Test Method is to specify a method to measure the concentration of the deep donor EL2 in SI GaAs by infrared absorption.


This Test Method covers a procedure for measuring the concentration of the deep donor EL2 in SI GaAs. This method focuses on improving the accuracy and repeatability of the measurement by standardizing the test conditions and reporting and by routine calibration of the measurement.

 

This Test Method is intended to cover SI GaAs samples with an electrical resistivity in the range from 1 × 106 to 5 × 108 Ω·cm, determined by doping with carbon. The concentration of EL2 must be greater than 5 × 1015 cm−3.
