摘要
The Na2KSb photocathode has a longer threshold wavelength than the K2CsSb photocathode. This contradicts the general experience that cathode materials containing Cs tend to have longer threshold wavelengths. An attempt is made to explain this contradiction in terms of the energy-band models for the two materials.
