the former might originate from linearly bonded co on the uncovered cu substrate surface. with increasing cr thickness, the latter high-frequency band becomes prominent. for the 0.3-nm-thick cr surface, the band at 2117 cm 1 dominates all spectra through co exposure. the tpd spectra of the cr-deposited cu surfaces show two remarkable features at 220 250 and 320 390 k, which are ascribable respectively to cu-co and cr-co bonds.
