Abstract
The electron affinity of thick dielectrics, of thickness greater than 10 nanometers, is measured by applying a polarization voltage varying between −4V and −40V, for example, and by taking several measuring points to determine a reference value of the photo-emission threshold (E), applying linear regression to an adjustment straight line () linking the measured thresholds () to the respective values of the square root of the voltage V.
