“…The fabricated device exhibited rectifying behaviour, indicating the diode formation, and the heterojunction showed potential for UV photodetection applications [36]. The use of organic materials provides a chance of fabricating flexible heterostructure [37][38][39]. However, the fabrication of n-ZnO/p-PANI heterojunction on a flexible substrate is still limited.…”

This study aims to develop and characterize a flexible p-PANI/n-ZnO heterojunction diode developed from a combination of electrochemical and sputtering technique. Investigation of structural properties and morphology of the thin films has been done from XRD and SEM analysis. To study the temperature effect on electrical properties of the diode, current-voltage–temperature (I–V–T) measurements were done for the temperature range 25-300 K. Applying the ideal thermionic emission theory, various diode parameters like reverse saturation current, quality factor, series resistance and barrier height were computed utilizing the semilogarithmic plot of I-V curve and Cheungs’ method. Barrier height, reverse saturation current and quality factor calculated from lnI versus V curve were observed to vary from 0.0627-0.725eV, 0.236-98.8 nA and 54.43–3.29 respectively over the temperature range 25-300 K. It has been found that the series resistance falls with a rise in temperature. The barrier height, series resistance and ideality factor were observed to vary from 0.0628-0.692 eV, 15,900-46.8 Kohm and 41.88-2.27 respectively for the temperature range 25–300 K. The activation energy estimated from Arrhenius plot was observed to be 14.51 meV. Additionally, the fabricated PANI/ZnO diode was mechanically robust that can be bent without affecting its performance.

Poly(vinylidene fluoride) (PVDF)‐based polymers demonstrate great potential for applications in flexible and wearable electronics but show low piezoelectric coefficients (e.g., −d33 < 30 pC N−1). The effective improvement for the piezoelectricity of PVDF is achieved by manipulating its semicrystalline structures. However, there is still a debate about which component is the primary contributor to piezoelectricity. Therefore, current methods to improve the piezoelectricity of PVDF can be classified into modulations of the amorphous phase, the crystalline region, and the crystalline–amorphous interface. Here, the basic principles and measurements of piezoelectric coefficients for soft polymers are first discussed. Then, three different categories of structural modulations are reviewed. In each category, the physical understanding and strategies to improve the piezoelectric performance of PVDF are discussed. In particular, the crucial role of the oriented amorphous fraction at the crystalline–amorphous interface in determining the piezoelectricity of PVDF is emphasized. At last, the future development of high performance piezoelectric polymers is outlooked.
