In the course of following the thermal desorption of CO adsorbed on Cu layers on W110, i.e. W110CunC0 by work function changes a substantial temperature coefficient of work function was noted for the substrates and investigated in some detail. Temperature coefficients of work function for Cu layers in the range 0 or 6 where n is the number of monolayers were measured from 90-500 K by a Kelvin probe method. d phid sub T is negative at all coverages and has a strong maximum of -.00015 evK at n 1 at 90 K. A qualitative discussion of these findings is given. The design and operating characteristics of the Kelvin probe are also described.
