Terahertz electro-optic properties of PbZr0.52Ti0.48O3 and BaTiO3 ferroelectric thin films

Probing Ultrafast Dynamics of Ferroelectrics by Time‐Resolved Pump‐Probe Spectroscopy

“…As the polarization can be coupled with other intrinsic properties as well as external stimuli, the ferroelectric exhibits various physical properties, and is considered as a critical component in modern and future electronic elements. [ 14 , 15 , 16 , 17 , 18 , 19 ] As shown in Figure 1b , under the external stimuli of electric, stress, light, and magnetic fields, the ferroelectric enjoys multiple coupling effects of piezoelectric, [ 20 ] electric‐optic, [ 21 , 22 , 23 ] magneto‐electric, [ 24 , 25 ] piezo‐magnetic, [ 26 ] and magneto‐optic [ 27 ] effects, among others. [ 28 , 29 , 30 ] Based on these unusual physical properties, the ferroelectric materials have been employed for widespread applications such as pyroelectric sensors, piezoelectric actuators, electro‐optic modulators, and nonvolatile memories, [ 28 , 29 , 30 ] and other novel applications following the exploration of unusual polarization domain structures have also been conceived.…”

In situ polarization and dielectric property measurements of Pb(Zr 0.52 Ti 0.48 )O 3 ferroelectric nanocrystals

“…Thin films always require special substrates, such as SrTiO 3 substrate [9, 10, 11]. The quality and crystallographic orientation of the films strongly influence the EO properties of thin films [12].…”

Large linear and nonlinear electro-optic coefficients in two-dimensional ferroelectrics

“…As such, EO effects have been intensively studied in recent years (see, e.g., Refs. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] and references therein). In particular, obtaining large linear but also nonlinear electro-optic coefficients are required for designing efficient and/or novel optical devices, including EO modulation [10], optical shutters [15], EO detection [17], and EO switching [19].…”
