Abstract
A method for the atomic absorption spectrometric determination of important impurities in indium phosphide (InP) is described. Results are compared with those obtained by glow discharge mass spectrometry. To avoid accidental contamination, no preconcentration was used:The detection limits are as low as 10(14)-10(16) atoms cm-3. This method gives the possibility of checking rapidly the amount of impurities in InP polycrystals and dopants in InP single crystals by a relatively inexpensive technique.File in questo prodotto:
