Work functions ranged from 2.67 eV to 3.32 eV with a shallow minimum at 40% by mass W and were relatively constant (~2.7-2.8 eV) in the range 30-70% by mass W. The decrease in work function was accompanied by a strong decrease in AR from 39.3 A cm⁻² K⁻² to 0.02 A cm⁻² K⁻² over the range 20-70% by mass W. The reduction in both φR and AR was associated with the major conversion of the surface to BaWO₄ and Ba₄Ti₁₂O₂₇ during the activation treatment before emission testing.]]> Sat 24 Mar 2018 07:10:24 AEDT ]]>
