When a radiofrequency potential is applied to an electrode such as gold in an electrolyte, ultrasound is generated at the interface. This effect is attributed to changes in the volume of the solution adjacent to the metal and can be used to study the structure of the interface. Preliminary measurements are reported as a function of the d.c. electrode potential. The effect is particularly sensitive to adsorbed species such as organics. Various means for enhancing the effect are discussed. Author
