“…NS are obtained by an exfoliation process of various layered oxides [31] and transferred by Langmuir-Blodgett (LB) method (Figure 1a,b) [32] on substrates that, when used bare, are non-adapted for complex oxide deposition, such as silicon or glass. The exceptionally rich structural diversity of NS makes them interesting growth templates for oxides [30,[33][34][35][36][37][38][39][40] or metals. [41] SVO has a cubic perovskite structure with a lattice parameter a = 0.384(1) nm [42] whereas CVO is orthorhombically (o) distorted with pseudo-cubic (pc) a pc = a o /√2 = b o /√2 = c o /2 ≈0.377(1) nm.…”

“…Polycrystalline BFO with preferential (100) PC orientation has been obtained on (111) Pt by means of a chemical solution route [239]. More recently, nanosheets of Ca 2 Nb 3 O 10 have been successfully used as a seed layer for highly oriented (100) PC BFO grown on Si [240]. BiFeO 3 films directly deposited on metallic substrates have not been intensively investigated.…”

Over the past four decades, energy microsources based on piezoelectric energy harvesting have been intensively studied for applications in autonomous sensor systems. The research is triggered by the quest for replacing standard lead-based piezoelectric ceramics with environmentally friendly lead-free materials and potential deployment of energy-harvesting microsystems in internet of things, internet of health, “place and leave” sensors in infrastructures and agriculture monitoring. Moreover, futher system miniaturization and co-integration of functions are required in line with a desired possibility to increase the harvested power density per material volume. Thus, further research efforts are necessary to develop more sustainable materials/systems with high-performance. This paper gives a comprehensive overview on the processing and functional testing the lead-free bulk materials and thin films and discuss their potential in the applications in the stress- and strain-driven piezoelectric energy harvesting. This includes the methodology of estimation of the substrate clamping and orientation/texture effects in the thin films, and identification of orientations offering high figure of merit. The ability to control film orientation of different lead-free materials is reviewed and the expected piezoelectric performances are compared with the ones reported in literature.

“…The PFM images represent switching behavior between perpendicular components of polarization, which can be divided into two states: dark and bright. The bright region corresponds with downward direction of polarization, which means that the polarization vector is oriented downward and associated with the [111] or [1][2][3][4][5][6][7][8][9][10][11] polarization direction [30]. Dark regions, on the other hand, are oriented upward and related [−1 -11] or [−111] direction [30].…”

“…The angle α is around 60 degrees [1]. Aside from having the unique combination of a magnetic and ferroelectric response, the material shows outstanding temperature stability with a high Curie [2] (Tc = 1120 K) point. The bismuth ferrite has a complex magnetic structure [3] due to interaction between its magnetic and electric dipoles [4].…”

Exploring the Piezoelectric Properties of Bismuth Ferrite Thin Films Using Piezoelectric Force Microscopy: A Case Study

et al. 2023

Over recent decades, the scientific community has managed to make great progress in the theoretical investigation and practical characterization of bismuth ferrite thin films. However, there is still much work to be completed in the field of magnetic property analysis. Under a normal operational temperature, the ferroelectric properties of bismuth ferrite could overcome the magnetic properties due to the robustness of ferroelectric alignment. Therefore, investigation of the ferroelectric domain structure is crucial for functionality of any potential devices. This paper reports deposition and analyzation of bismuth ferrite thin films by Piezoresponse Force Microscopy (PFM) and XPS methods, aiming to provide a characterization of deposited thin films. In this paper, thin films of 100 nm thick bismuth ferrite material were prepared by pulsed laser deposition on multilayer substrates Pt/Ti(TiO2)/Si. Our main purpose for the PFM investigation in this paper is to determine which magnetic pattern will be observed on Pt/Ti/Si and Pt/TiO2/Si multilayer substrates under certain deposition parameters by utilizing the PLD method and using samples of a deposited thickness of 100 nm. It was also important to determine how strong the measured piezoelectric response will be, considering parameters mentioned previously. By establishing a clear understanding of how prepared thin films react on various biases, we have provided a foundation for future research involving the formation of piezoelectric grains, thickness-dependent domain wall formations, and the effect of the substrate topology on the magnetic properties of bismuth ferrite films.
