“…In addition, as shown in Figure 6c, the speckle-shaped nanometer-sized (<100 nm) domains are compact and uniform. The domain wall motion can occur easily owing to the smaller domains, thus revealing the high piezoelectric activity of the PMN-PT samples [28,35]. In comparison, the domain structure near the kerf, as shown in Figure 6f, is similar to that in Figure 6c.…”

A decrease of piezoelectric properties in the fabrication of ultra-small Pb(Mg1/3Nb2/3)–x%PbTiO3 (PMN–x%PT) for high-frequency (>20 MHz) ultrasonic array transducers remains an urgent problem. Here, PMN–31%PT with micron-sized kerfs and high piezoelectric performance was micromachined using a 355 nm laser. We studied the kerf profile as a function of laser parameters, revealing that micron-sized kerfs with designated profiles and fewer micro-cracks can be obtained by optimizing the laser parameters. The domain morphology of micromachined PMN–31%PT was thoroughly analyzed to validate the superior piezoelectric performance maintained near the kerfs. A high piezoresponse of the samples after micromachining was also successfully demonstrated by determining the effective piezoelectric coefficient (d33*~1200 pm/V). Our results are promising for fabricating superior PMN–31%PT and other piezoelectric high-frequency (>20 MHz) ultrasonic array transducers.

“…One such material is Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) [1,2] which has outstanding physical properties, such as piezoelectric, pyroelectric, and electrooptic properties [3]. PMN-PT has important applications, such as in ultrasound transducers including medical ultrasonic transducers and underwater acoustic transducers; sensors such as accelerometers and hydrophones; actuators such as stack/in-plane actuators, flextensional actuators and resonant actuators; energy-harvesting applications; and optoelectronics devices, such as light shutters, color filters, modulators, displays, and image storage devices [3,4].…”

Multi‐scale domain structure observation and piezoelectric responses for [001]‐oriented PMN‐33PT single crystal

Multiple phase coexistence contributes to the extraordinary piezoelectric behavior of (1‐x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN–xPT) near the morphotropic phase boundaries (MPBs). By incorporating an optical path of crossed polarized light (PLM) into the commercialized Piezoelectric Force Microscope (PFM) (named as PLM‐PFM system), in situ domain structure observation from micro‐ to nanoscale, as well as measurement of the piezoelectric behavior for individual domains can be realized. For [001]‐oriented single crystal of 67Pb(Mg1/3Nb2/3)O3‐33PbTiO3 (PMN‐33PT), fine domain boundary structures of rhombohedral (R), tetragonal (T), and monoclinic (M) phases are revealed. Measurements of the electric field‐induced displacement as a function of the applied DC electric field (VDC) are performed for domains with different polarization vectors. Values for the electric field‐induced displacement are in descending order for c‐domains of the M, R, and T phases. For an individual phase of T or M, the displacement increases when the angle between the polarization vector and the applied electric field decreases. The multi‐scale perspective of the domain structures and the corresponding piezoelectric response helps in understanding the ultra‐high piezoelectric performance for PMN‐PT single crystals near MPB.
