摘要：

Electron spectroscopic investigations are used to show that defects at various concentrations are inherently present on surfaces of KNbO//3 crystals. Their concentration at the surface is determined by the bulk concentration as well as by diffusion. These defects are important for most classical measurements on KNbO//3 and similar materials.
