Innovative methods to fabricate and integrate biodegradable high-grade electronics on green substrates are needed for the next generation of robust high-performance transient electronics. This is also needed to alleviate the growing problem of electronic waste (e-waste). Herein, the authors present the n-channel silicon (Si) nanoribbons-based high-performance transistors developed on biodegradable metal (magnesium) foils using the direct transfer printing method. The developed transistors present high effective mobility of >600 cm2 V−1 s−1, high on/off current ratio (Ion/off) of >104, negligible hysteresis, transconductance of 0.19 mS, and an on-current of 1.6 mA at a bias of 2 V. Further, the transistors show stable device performance under temperature stress (5–50 °C), gate-bias stress, continuous long-term transfer scans for 24 h (>3000 cycles), and aging test (up to 100 days) demonstrating the excellent potential for futuristic high-performance robust transient devices and circuits. Finally, the effect of transience on the electrical functioning of devices on Mg foils (at pH 8) and degradation of Mg foils at different pH values is studied by hydrolysis. The outcome from these experiments demonstrates the potential of direct transfer printing for high-performance transient electronics and also as the new avenue toward zero e-waste.
