8. of application for this technology Sauerbrey Equation Sauerbrey s equation is often used to calculate mass loadings and thin film thicknesses in vacuum depositions The basic assumption is that the incremental change in mass from the foreign film is treated as though it were really an extension of the thickness of the underlying quartz The foreign film is considered rigid and so thin that it does not experience any shear forces during vibration As a result the sensitivity factor S is a fundamental property of the quartz crystal and does not consider any of the properties of the foreign film i e it is only dependent on the acousto elastic properties of quartz By means of Sauerbray Equation mass per unit area M in function of resonance Frequency shift Av S is crystal sensitivity AE QCM 2 0 User Manual v 1 0 QCM Measurements i 8 novaetech 8 The dependence of the frequency change on the mass coverage per unit area emphasizes the fact that within certain limits the sensitivity factor is independent of the electrode geometry Thus in theory the QCM mass sensor does not require calibration for this application This ability to calculate mass loading from first principles is obviously a very attractive feature of these devices Film thickness Film thickness is often the parameter of interest in gas phase thin film depositions If the mass coverage is believed to be uniform the thickness t of the film is easily calculate
