The distribution of oxide species in the Cs ∕ O activation layer on InP(100) negative electron affinity photocathodes

The atomic arrangement of Cs oxides in the activation layer of an InP photocathode is investigated using angle dependent photoemission spectroscopy. Two distinct peaks in the O 1 s core level and in valence band spectra have led to the discovery of two molecular oxygen species incorporated in the th...
