“…The use of pure metal based sources has been already proven to be effective in yielding photocathodes with quantum efficiency comparable to the ones grown in sealed tubes, 13 but the handling of pure metals has to be performed in inert gas atmosphere because of the well-known reactivity of alkali metal in their pure state.

The authors report on successful growth of bialkali photocathode based on CsK 2 Sb using the alkali metal vapors generated by thermal decomposition of alkali azides. Details about the ultrahigh vacuum growth system and the procedure used are provided. The final quantum efficiency of the photocathode under illumination with 532 nm laser is 9.6%. This value is comparable to the largest ones obtained in our previous experiments using commercial dispensers, indicating that alkali azides are a viable alternative.

The authors report on the growth of Na2KSb bialkali and Na2KSb:Cs3Sb multialkali photocathodes using the vapors generated by evaporating pure metals with effusion cells under vacuum conditions. Details about the ultrahigh vacuum growth system and the used procedures are provided. The new growth system is capable of growing over large areas with uniform photoemission properties using different types of substrates. The measured spectral response curves indicate that high quality photocathodes are produced with peak quantum efficiencies well above 20%. Procedures to obtain multialkali photocathodes with extended sensitivity into the infrared range (well above 800 nm) are described.
