Abstract
In the present study some of the methods developed for the experimental determination of (interfacial or film) stress changes in electrochemical systems containing solid-liquid interfaces are briefly reviewed, as well as the kind and quality of information that can be obtained using these methods are discussed. The “bending beam” (“bending cantilever”, “laser beam deflection”, “wafer curvature”) method and related techniques, the piezoelectric method, the extensometer method, and the method based on the measurement of contact angle are discussed in detail. Special attention has been paid to problems related to the use of optical methods for position sensing.
Zusammenfassung
Die vorgestellte Studie stellt einige der Methoden vor, die in elektrochemischen Systemen zur experimentellen Bestimmung der Grenzflächenspannungen an den Phasengrenzen flüssig/fest von Elektroden oder darauf lokalisierten Filmen genutzt werden können. Darüber hinaus werden die Resultate der Verfahren im Hinblick auf Art und Qualität ihrer Aussage bewertet. Sowohl optische Verfahren zur Messung der Krümmung (,,bending cantilever“, ,,laser beam deflection“, ,,wafer curvature“) und vergleichbare Techniken, als auch das piezoelektrische Verfahren, die Nutzung eines Extensometers und die Messung des Kontaktwinkels werden detailliert diskutiert. Besonderes Augenmerk wurde bei den optischen Verfahren auf die der Darstellung der Notwendigkeit der genauen Kenntnis der Positionierung der einzelnen Komponenten gelegt.
Funding statement: This research has received funding from the Hungarian Scientific Research Fund (OTKA) under Grant Agreement number K 109036.
