However, because K{sub 2}CsSb is easily contaminated and has a half-life of less than a day when in use, switching to a more rugged high quantum efficiency (QE) material such as Cs{sub 2}Te is …

WebbThe purity of the gas is very important, being typically 1 part in 105. Certain impurities such as oxygen, water vapour and some halogens have a high electron affinity and must be kept from poisoning the gas. If an atom or molecule captures an electron and becomes a negative ion, the associated drifted velocity becomes very small; this is typically Webb10 okt. 2024 · These materials typically consist of three alkali atoms and one antinomy atom per molecule, and some photocathodes (such as the S-20) use multiple layers of differing composition. Commonly used photocathodes of this family include Cs 3 Sb, K 2 CsSb, Na 2 KSb, and (Cs) Na 2 KSb (S20), though others are used as well. pork producers recipes
