“…This is because interlayer sliding adequately releases the strain in the epitaxial layer and makes the film exceptionally flexible. 23 More importantly, the temperature tolerance of mica could reach up to 750 °C, which favors the crystallization of Ga 2 O 3 during the epitaxial growth. Recently, Tak et al and Sui et al fabricated a Ga 2 O 3 PD on a mica substrate, but the devices all showed poor performance and had drawbacks such as polycrystallinity.…”

Flexible Ga 2 O 3 photodetectors have attracted considerable interest owing to their potential use in the development of implantable, foldable, and wearable optoelectronics. In particular, β-phase Ga 2 O 3 has been most widely investigated due to the highest thermodynamic stability. However, high-quality β-phase Ga 2 O 3 relies on the ultrahigh crystallization temperature (usually ≥750 °C), beyond the thermal tolerance of most flexible substrates. In this work, we epitaxially grow a high-quality metastable κphase Ga 2 O 3 (002) thin film on a flexible mica (001) substrate under 680 °C and develop a flexible κ-Ga 2 O 3 thin film photodetector with ultrahigh performance. Epitaxial κ-Ga 2 O 3 and the mica substrate are maintained to be thermally stable up to 750 °C, suggesting their potential for harsh environment applications. The responsivity, on/off ratio, detectivity, and external quantum efficiency of the fabricated photodetector are 703 A/W, 1.66 × 10 7 , 4.08 × 10 14 Jones, and 3.49 × 10 5 %, respectively, for 250 nm incident light and a 20 V bias voltage. These values are record-high values reported to date for flexible Ga 2 O 3 photodetectors. Furthermore, the flexible photodetector shows robust flexibility for bending radii of 1, 2, and 3 cm. More importantly, it shows strong mechanical stability against 10,000 bending test cycles. These results reveal the significance of high-quality κ-phase Ga 2 O 3 grown heteroepitaxially on a flexible mica substrate, especially its potential for use in future flexible solar-blind detection systems.

“…The rapid development of flexible electronics triggered a high demand for energy storage devices with high safety and energy density, as well as low cost. [1][2][3][4][5] In this context, zinc-ion batteries (ZIBs) have received much attention due to their high safety and environmental friendliness, and the natural abundance of Zn. [6][7][8][9][10][11] Metallic Zn is the most common anode material for ZIBs.…”

“…Historically, research on designing flexible electronic materials and their heterostructures involves various polymeric substrates, for example, polyimide (PI), polyethylene terephthalate (PET), and polydimethylsiloxane (PDMS), which offer suitable mechanical characteristics for various device applications [26,27]. However, fabrication of flexible thin films and heterostructures of inorganic ferroic oxides on polymeric flexible substrates involves several process challenges, such as insufficient thermal stability of the substrates at the high growth temperature, required for inorganic oxide layers, their lattice mismatch, and the very fact that the inorganic oxide layers are brittle in nature [28]. In order to circumvent the challenges, various preparation strategies have been developed to combine inorganic multiferroic oxides and the flexible polymeric substrates.…”

“…Of late, mica has been explored as a viable choice for direct growth of the inorganic functional layers. The van der Waals nature of the bond between the functional oxide layers with mica lifts the complications related to strain originating due to lattice mismatch [28]. Mica, which belongs to the phyllosilicate family, exhibits several key advantages, including chemical inertness, mechanical flexibility, atomically smooth surface, high transparency, and high thermal stability in ultrathin sheets.…”

A great deal of interest has grown in both academia and industry toward flexible multiferroics in the recent years. The coupling of ferromagnetic properties with ferroelectric properties in multiferroic materials opens up many opportunities in applications such as magnetoelectric random access memories, magnetic field sensors, and energy harvesters. Multiferroic materials on a flexible platform bring an exciting opportunity for the next generation of consumer electronics owing to their unique characteristics of wearability, portability, and weight reduction. However, the fabrication of flexible multiferroic devices is still a great challenge due to various technical difficulties, including the requirement of high growth temperature of the oxide-based multiferroic materials, their lattice mismatch with the flexible substrates, and the brittleness of the functional layers. In this review article, we will discuss different methods of fabricating flexible or even freestanding oxide films to achieve flexible electronics. This article will address the benefits and challenges of each synthesis method in terms of interlayer interactions and growth parameters. Furthermore, the article will include an account of the possible bending limits of different flexible substrates without degrading the properties of the functional layer. Finally, we will address the challenges, opportunities, and future research directions in flexible multiferroics.
