| 1 | Biodegradable Flexible Organic Field-Effect Transistors | The use of natural material components in organic devices increases nature friendliness and biodegradability. In this paper, water-soluble natural protein gelatin is explored as a gate dielectric for demonstration of high performance and low voltage (−3 V) operation in flexible organic field-effect transistors (OFETs). The fabricated p-channel devices showed excellent electrical characteristics of maximum field-effect mobility up to 3.0 cm² V⁻¹ s⁻¹, high current on/off ratios, low subthreshold swing, and nearly zero threshold voltage due to the high-quality dielectric semiconductor interface achieved through optimized processes of fabricating flexible OFET devices. These devices exhibited very high operational stability as confirmed by various stability tests including bias-stress, repeatability, electromechanical stability, cyclic stability, and long-term ambient stability. For electromechanical stability, no significant changes in the performance were observed upon application of compressive and tensile strain due to bending. A very high environmental stability with almost unchanged electrical characteristics over 24 weeks was demonstrated. Further, circuit applicability was analyzed by switching characteristics from resistive load inverters. These results indicate gelatin as a promising biodegradable dielectric candidate for low voltage flexible OFETs. | Link |
| 2 | Eco-sustainable FET with Natural polysaccharide | In this paper, firstly, reports on use of various nature originated polysaccharides as gate dielectric candidates for organic field effect transistors (OFETs) to achieve eco-friendliness and eventual biodegradability in devices, are summarized. To emphasize the same, the performance of flexible OFETs fabricated with cyanoethyl cellulose (CEC), a synthetically modified cellulose as gate dielectric is comprehensively investigated. A widely studied TIPS-pentacene: PS blend is used to form the active layer in these devices, showing a p-channel transistor operation at a low voltage of −5 V. Along with high performance, these devices exhibited excellent repeatability and shelf life up to 10 months in ambient conditions. Effect of repeatability, bias-stress, and bending stability were investigated to confirm the decent electrical and bending stability. The device can sustain the transistor performance even after application of 200 bending cycles. Moreover, the effect of annealing temperature on transistor performance was studied to observe their suitability in real applications. These findings suggest that polysaccharides can be suitable gate dielectric for eco-sustainable electronics. | Link |

| 5 | Anisotropic functionalized filler driven interfacial charge orchestration in elastomer composite based TENG for wireless communication | There is a surge in research in the domain of polymer nanocomposite-based triboelectric nanogenerators (TENG), yet, underpinning the influence of embedded nanomaterials, their functionalities, and interaction with polymer functional groups towards controlling the TENG output remains limited, especially in cases involving anisotropic fillers like carbon nanotubes. In this work, we investigate a model comprising amine-modified multiwalled carbon nanotubes and maleic anhydride functionalized liquid rubber for interfacial charge orchestration. We decoded how bidirectional electrical conductivity, charge dispersion, and dielectric properties can synergistically govern the TENG outcome. An empirical mathematical equation was established to correlate the dielectric properties, directional conductivities, and TENG output. The fitted curve demonstrated strong agreement with experimental data. The optimized TENG device, stable over 30,000 cycles, demonstrated an open-circuit voltage of 253.23 V, short-circuit current of 71.13 μA, short-circuit charge of 92.48 nC, and a power density of 7.70 W/m2, surpassing existing CNT-polymer-based systems. Finally, the TENG devices were utilized to develop a remote that can control the various electronic devices without any internet within the range of ~400 m. This work not only advances material-level insight into anisotropic nanocomposites for TENG but also acts as an enabler for sustainable energy and intelligent device interfacing. | Link |
