Key Points

Investigate the low-frequency polarization dynamics and quantify piezoelectric and electrostrictive contributions in KH2PO4 crystals near their phase transition.
Measured low-frequency polarization dynamics in KH2PO4 crystals as a function of temperature.
Characterized the emergence of piezoelectric and electrostrictive coupling effects across the transition region.
Piezoelectric and electrostrictive contributions to low-frequency polarization dynamics increase substantially when temperature falls below 135.1 K.
Electromechanical coupling mechanisms become dominant drivers of low-frequency dielectric oscillations in the low-temperature regime.

Implication

Experimental analysis reveals marked piezoelectric and electrostrictive contributions in KH2PO4 crystals below 135.1 K, indicating strong electromechanical coupling near phase transition.

Abstract

The piezoelectric and electrostrictive contributions to the low frequency dynamics of polarization in KH2PO4 crystals are studied. The contributions start to become very significant when the temperature falls below 135.1 K.
