Background:

Two-dimensional (2D) materials exhibit piezoelectricity, crucial for electromechanical coupling applications.
Existing methods primarily measure out-of-plane piezoelectricity, limiting quantitative in-plane analysis.
In-plane piezoelectric coupling is dominant in many 2D materials but challenging to measure.

Purpose of the Study:

To introduce a novel technique for quantitatively probing in-plane piezoelectric coupling in 2D materials.
To enable precise measurement of in-plane piezoelectric coefficients in layered nanomaterials.
To validate the technique using molybdenum disulfide (MoS2) as a model system.

Main Methods:

Development of a lateral Piezoresponse Force Microscopy (PFM) approach with in-plane field excitation.
Operation near the cantilever's contact resonance frequency for enhanced sensitivity (sub pm/V).
Detailed signal calibration and background subtraction protocols for accurate measurements.

Main Results:

Successfully measured in-plane piezoelectric coefficients (d11) for suspended MoS2 flakes (1-5 layers).
Observed finite d11 values for odd-layered, non-centrosymmetric MoS2, confirming in-plane response.
Demonstrated a decrease in piezoelectric coupling strength with an increasing number of atomic layers.

Conclusions:

The developed lateral PFM technique provides a quantitative method to study in-plane piezoelectricity.
This approach is effective for characterizing emerging 2D materials and understanding their electromechanical properties.
The findings offer insights into layer-dependent piezoelectric behavior in 2D materials.
