Secondary-ion mass spectrometry of the superconducting Bi–Pb–Sr–Ca–Cu–O system
Abstract
Secondary ion mass spectrometry has been used to examine the surface of the superconducting material Bi2 –xPbxSr2Ca2Cu3Oy Some surface reaction with moisture was evident. Ion energy spectra have been used to interpret ambiguous mass spectra due to interference of peaks. Additional data are presented for the MO+ intensity ratio–dissociation energy relationship.
