Abstract
Centrifuge measurements have been carried out which show a significant contribution of the electrostatic double layer to adhesion between solids. By variation of the illumination of the adhesive system, Zr-coated gold spheres on CdS single-crystals, the electronic properties of the photoconducting CdS and hence the electrostatic double layer force at the interface are varied whereas other forces (van der Waals, H2O layer) remain unaffected. Qualitatively, the experimental results are in agreement with a simple model of the metal-semiconductor contact. Either surface contaminants or surface asperities would prevent quantitative agreement with this theory.Keywords
