Low-Frequency Vibration Sensor with a Sub-nm Sensitivity Using a Bidomain Lithium Niobate Crystal

We present a low-frequency sensor for the detection of vibrations, with a sub-nm amplitude, based on a cantilever made of a single-crystalline lithium niobate (LiNbO<sub>3</sub>) plate, with a bidomain ferroelectric structure. The sensitivity of the sensor-to-sinusoidal vibrational excit...
