Fig. 2.18 a Calculated temperature dependence of work function of Na. The full and dashed lines
indicate the thermal expansion effect and the lattice vibration effect, respectively [17]. b Calculated
temperature dependence of work function of Al. The full and dashed lines indicate the thermal
expansion effect and the lattice vibration effect, respectively [17]. c Calculated temperature dependence of work function of Cu. The full and dashed lines indicate the thermal expansion effect and
the lattice vibration effect, respectively [17]
