“…Piezoelectric materials are materials that accumulate electrical charge in response to applied mechanical stress. They can be classified as natural (e.g., berlinite, quartz, topaz, etc.) or synthetic (e.g., BaTiO 3 , PbTiO 3 , lead zirconate titanate (PZT), ZnO, poly(vinylidene fluoride) (PVDF), etc.).…”

We report the effects of various substrates and substrate thicknesses on electrospun poly(vinylidene fluoride) (PVDF)-nanofiber-based energy harvesters. The electrospun PVDF nanofibers showed an average diameter of 84.6 ± 23.5 nm. A high relative β-phase fraction (85.2%) was achieved by applying high voltage during electrospinning. The prepared PVDF nanofibers thus generated considerable piezoelectric potential in accordance with the sound-driven mechanical vibrations of the substrates. Slide glass, poly(ethylene terephthalate), poly(ethylene naphthalate), and paper substrates were used to investigate the effects of the intrinsic and extrinsic substrate properties on the piezoelectricity of the energy harvesters. The thinnest paper substrate (66 μm) with a moderate Young's modulus showed the highest voltage output (0.4885 V). We used high-performance 76, 66, and 33 μm thick papers to determine the effect of paper thickness on the output voltage. The thinnest paper substrate resulted in the highest voltage output (0.7781 V), and the numerical analyses of the sound-driven mechanical deformation strongly support the hypothesis that substrate thickness has a considerable effect on piezoelectric performance.

“…Interestingly both SiH and GeH exhibit buckled honeycomb like structures under ambient condition and find extensive applications as efficient photocatalysts for water splitting [28][29][30][31][32]. Moreover, these materials show piezoelectric behavior and successfully used as 2D transistors [33][34][35][36]. While SiH shows an indirect band gap (E g ) of ∼2.…”

The present paper is primarily focused to understand the strain driven alterations in thermoelectric properties of two-dimensional SiH and GeH monolayers from first-principle calculations. Electronic band structures and the associated thermoelectric properties of the compounds under ambient and external strains have been critically unveiled in terms of Seebeck coefficients, electrical conductivities, power factors and electronic thermal conductivities. The phonon dispersion relations have also been investigated to estimate the lattice thermal conductivities of the systems. The thermoelectric figure of merits of SiH and GeH monolayers under ambient and external strains have been explored from the collective effects of their Seebeck coefficients, electrical conductivities, electronic and lattice thermal conductivities. The present study will be helpful in exploring the strain induced thermoelectric responses of SiH and GeH compounds which in turn may bear potential applications in clean and global energy conservation.

“…Aluminum phosphate (AlP x O y ) thin films have been explored for a wide variety of applications such as catalyst support, , electrode coating to improve both safety and cycle performance of lithium ion battery cathodes, − thin film dielectric, − and oxidation resistant coating for carbonaceous materials. , Film uniformity and conformality are highly relevant for the practical application of aluminum phosphate, especially when deposition on 3D structures is required. The latter case applies, for example, to the field of 3D Li-ion batteries where AlP x O y is used to coat cathode particles, , or in the case of oxidation resistant coatings on fibers or carbon nanotubes. , In addition, the ability to tune the composition has been shown to play a critical role for aluminum phosphate thin films.…”

Atomic Layer Deposition of Aluminum Phosphate Using AlMe₃, PO(OMe)₃, and O₂ Plasma: Film Growth and Surface Reactions

High purity, uniform, and conformal aluminum phosphate (AlPxO y ) thin films were deposited by atomic layer deposition (ALD) between 25 and 300 °C using supercycles consisting of (i) PO(OMe)3 dosing combined with O2 plasma exposure and (ii) AlMe3 dosing followed by O2 plasma exposure. In situ spectroscopic ellipsometry and mass spectrometry were applied to demonstrate the ALD self-limiting behavior and to gain insight into the surface reactions during the precursor and coreactant exposures, respectively. Compared to earlier reported AlPxO y ALD studies using H2O and O3 as coreactants or without using coreactans, the use of an oxygen plasma generally leads to higher growth per cycle values and promotes phosphorus incorporation in the film. Specifically, when using a 1:1 PO x :Al2O3 cycle ratio and a substrate temperature of 150 °C, the growth per supercycle is found to be 1.8 Å. The [P]:[Al] atomic ratio for this process is approximately 0.5 (∼AlP0.5O2.9) and can be tailored by changing the ratio between the two cycles or the substrate temperature. In literature reports where the same aluminum precursor was used, the [P]:[Al] atomic ratio was limited to 0.2 or a very high number of phosphorus cycles was needed in order to increase the phosphorus content. Instead, we demonstrate deposition of films with a composition close to AlPO4 by using a 2:1 PO x :Al2O3 cycle ratio. The limited incorporation of P in the film is suspected to derive from the steric hindrance of the relatively bulky phosphorus precursor. Mass spectrometry suggests that the PO(OMe)3 precursor chemisorbs on the surface without the release of reaction products into the gas phase, whereas Al(Me)3 already undergoes methyl ligand abstraction upon chemisorption.
