Determination of oxygen content in germanium and silicon by activation with He3 ions

Determination of oxygen concentration in silicon and germanium by infrared absorption

“…Also the oxygen content in silicon as determined by 3 He activitation [11] was about twice that found by infrared absorption.…”

Database for and statistical analysisof the interlaboratory determination of the conversion coefficient for the measurement of the interstitial oxygen content of silicon by infrared absorption

“…Fuller [4][5] proposes the following model where both types of measurements are subject to random error; namely,…”

“…Given the model defined in eq (4)(5)(6), Fuller has shown that the ordinary least-squares estimate of the slope C is biased towards zero. The bias, in this case, is approximately -0.005/ig/g and is not significant for this study.…”

“…In addition to the test squares that were specifically prepared for this study, 21 specimens, grouped into three test sets which had been used in an earlier Japanese study [4][5][6] were made available for the current international study. The analysis is restricted to data on JEIDA set 1 which was measured by four absolute laboratories.…”

“…Provide a hard copy of the spectrum over the range to 1300 cm^on an expanded transmittance scale, with an interval of at least 1%/inch (0.5%/cm is preferred). 4. Determine mid-scale linearity.…”
