摘要：
We have observed the photoemission of electrons from metallic electrodes (platinum, copper, gold and aluminium) into poly-N-vinylcarbazole (PVK). The experiments showed that the threshold values of internal photoemission change according to the work function of the metal and allowed us to determine the PVK band gap. We obtained a value of about 5.3 eV which is 0.7 eV greater than that obtained in previous calculations in which the polarization energy of PVK was probably overestimated. © 1979.
