“…In this study, orthoferrite EuFeO 3 (hereafter, EFO) has been considered for investigating the disorder-coupling parameter via RS and OAS techniques. The perovskite oxides possess intriguing physical properties that make them potential candidates for various technological applications. − Especially, the rare earth orthoferrite (RFeO 3 ) family of such materials has been of much interest in spintronics, multiferroics, magneto-optics, photovoltaics and even in manipulating the electromagnetic waves due to its tunable electronic, optical, and magnetoelastic behavior. − Being correlated systems, these materials are also of interest for fundamental studies. − In addition, the band gap of this family lies in the visible region, which may also provoke the resonant scattering. Such processes could certainly affect the EPIs existing in the system .…”

The individual impact of disorder on different phonon modes has been investigated for orthoferrite EuFeO 3 by perceiving a correlation between temperature-dependent Raman linewidth ( ) and Urbach energy (E U ). It has been found that the plot of versus E U exhibits a linear relationship, whose slope (ξ) differs for each Raman mode. Interestingly, the Raman mode exhibiting larger temperature variation in width is found to acquire a larger slope. This has been understood as eclectic contribution of disorder toward altering the mode-widths. Furthermore, a careful analysis hints that parameter ξ may contain information of overlap between discrete (phonon) and electronic continuum (∼Urbach tail) states. This may be seen as a selective impact of disorder on individual phonons in view of the electron−phonon interaction. Hence, the slope of the linear plot between and E U has been realized as a parameter that may represent the individual disorder contribution to modify Raman width of each mode, and thereby ξ has been interpreted to be the disorder-coupling parameter.

“…The relative concentrations of the three types of oxygen are summaried in Table 2. The electrochemical performance depends on oxygen vacancy concentration of electrode materials [37] . This is because the higher concentration of O 2 species makes the adsorption capacity of OH − easier, thus accelerating the kinetics of surface redox reactions [38] .…”

With the advantages of short charging and discharging times, high power density, and long cycle life, supercapacitors are regarded as one of the most promising energy storage devices and have garnered massive attention in the field of energy storage. This paper prepared La1−xCaxMnO3 (x=0, 0.05, 0.1, 0.15, and 0.2) nanoparticles by the sol‐gel method. The microstructure, morphology, and electrochemical performance of the samples were characterized. The results depict that La0.85Ca0.15MnO3 has a low charge transfer resistance (0.19 Ω) and a large specific surface area (38.79 m2 g−1). The maximum specific capacitance of the La0.85Ca0.15MnO3 sample reached 248 F/g at a current density of 0.5 A/g, which is ascribable to its large specific surface area and high oxygen vacancy concentration. The anion‐intercalation mechanism was investigated by the charging and discharging process. The above results depict that Ca‐doping significantly enhances the electrochemical performance of LaMnO3 system.

promising prospects for next-generation consumer electronics in these devices, forming a bridge between traditional capacitor and battery, demonstrating quick charging/discharging, excellent cyclic stabilities, higher power densities, environment benignancy, low maintenance cost, long lifespan, and safety. [2,3] The technological advancement in consumer electronics for smart wearables has led to the innovation of bendable displays, flexible mobile phones, fitness bands, electronic skin, and smartwatches. [4][5][6] Additionally, in remote areas having inadequate power supply and scarcity of other energy reservoirs, self-powered dynamic devices have emerged as independent and self-sustainable systems for future electronics. The sustainability of these systems without any external storage system like batteries/ fuel cells minimizes the bulkiness of the system, thereby making them flexible for a variety of applications. [7][8][9] Flexible allsolid-state self-chargeable supercapacitors are a potential candidate for the new emerging wearable energy storage devices. They are safe, thin, lightweight, extremely flexible, and inexpensive. [10,11] These supercapacitors are based on wearable electronics technology, involving no power or charging source, but they suffer from poor performance. Furthermore, in contrast to traditional supercapacitors, the allsolid-state supercapacitors eliminate the risk of electrolyte spilling as well as short-circuiting between the electrodes. [12] Recently, self-powered stretchable systems or sensing platforms have been gaining popularity. Zhang et al. [13] designed an all-in-one stretchable self-powered system using a gold (Au)based triboelectric nanogenerator and stretchable graphenebased strain sensor. The coupled design principle of electronic materials and device architecture provides a promising method to develop high-performance wearable/stretchable energy storage devices and self-powered stretchable systems for future bio-integrated electronics. Practical applications of next-generation stretchable electronics hinge on developing sustained power supplies to drive highly sensitive on-skin sensors and wireless transmission modules. In another experiment, a low-cost, scalable, and facile manufacturing approach based on laser-induced graphene foams was used to fabricate a self-powered wireless sensing platform. [14] It generated stableThe demand for flexible supercapacitor sustaining green energy can go a long way in mitigating the issue of no power source in wearable electronics. Herein, a novel strategy is used to develop a self-charging supercapacitor using lead-free perovskites as piezoelectrodes and polyvinyl alcohol-potassium hydroxide (PVA-KOH) film as ionogelled electrolyte. This approach is unique as the existing conventional self-powered devices are based only on piezoelectric electrolytes. The all-solid-state supercapacitor is asymmetric, with nickel stannate (NiSnO 3 ) acting as the positrode and ferrous stannate (FeSnO 3 ) as the negatrode. These materials are non-toxic, envi...
