| Abstract | In cleaningcoppersurfacesby ion bombardment andannealing,carbonappears very often as a final contaminantwhich is very difficult to eliminate totally comparedwith other contaminants(0, S, Cl). Even during ion bombardment, surfaces are easily contaminatedby carbonandthe degreeof contaminationdependson the cleaningconditions.The main causeof the contaminationmay be the decomposition of hydrocarbonsof the residualgas [1,2]. In spite of this frequentlyoccurringcontaminationby carbon,to our knowledge systematicstudiesof carbon on coppersurfaceshavenot beenpublished.Only a LEED observationof a carbon superstructureon Cu(100) [2] andametaldeposition studyon Cu(100),contaminatedby carbon[3] havebeenreported.In this paperwe presentresultsof a LEED—AES studyon Cu(1 11) andCu(l 10),bothat different carboncoverages.To estimatethecarboncoveragethe co-adsorptionof oxygen on Cu(1 10) coveredby carbonwasalso studied. In contrastwith carbon,the adsorptionof oxygenon coppersurfaceshasbeen extensivelystudiedby many authorsusing various surface analytical techniques, suchas LEED, AES, XPS, UPS,ELS, ellipsometryandwork functionmeasurements. For recentreviews cf. refs. [4,51. In this paperadditionaldataon theadsorptionof oxygenon Cu(1 10), obtainedby LEED andAES, are reported. |
