⚖️ Quartz Crystal Microbalance: Sauerbrey Shift During Film Deposition (2D chamber)

2D cross-section of a vacuum deposition chamber with a quartz crystal microbalance: watch a film grow while the 5 MHz resonance drops by the Sauerbrey shift, with temperature drift, quality factor and desorption. Same QCMEngine module as the 3D page, with three numerical checks.
