EnSO “Energy for Smart Objects” project is focusing on autonomous micro energy sources (AMES) in the context of Internet of Things (IoT) smart objects emerging market. IoT is a concept where every day’s objects will be able to communicate together and are connected through Internet. A key element is the electronic hardware based on several building blocks, such as sensors, actuators, micro controllers, communication interfaces, power conditioning ICs, energy harvesters and storage Devices. These Smart objects have to be autonomous, easy to use and handle, as small as possible, robust and long lasting with a long operating life time! Whatever they will be, there is always a key ingredient for all the electronic systems which is the need to be powered with a minimum of energy.

The production of high quality semiconducting nanostructures with optimized electrical, optical and electromechanical properties is important for the advancement of next-generation technologies. In this context, we herein report on highly obliquely aligned single-crystalline zinc oxide nanosheets (ZnO NSs) grown via the vapor-liquid-solid approach using r-plane (01-12) sapphire as the template surface. The high structural and optical quality of as-grown ZnO NSs has been confirmed using high resolution transmission electron microscopy and temperature-dependent photoluminescence, respectively. To assess the potential of our NSs as effective building materials in high performance flexible electronics, we fabricate organic (parylene C) / inorganic (ZnO NS) hybrid field-effect transistor (FET) devices on flexible substrates using room temperature assembly processes. Extraction of key FET performance parameters suggest that as-grown ZnO NSs can successfully function as excellent n-type semiconducting modules. Such devices are found to consistently show very high on-state currents (Ion) > 40 µA, high field-effect mobility (µeff) > 200 cm2/Vs, exceptionally high on/off current modulation ratio (Ion/off) of around 109, steep sub-threhold swing (s-s) < 200 mV/decade, very low hysteresis and negligible threshold voltage shifts with prolonged electrical stressing (up to 340 min). The present study delivers a concept of integrating high quality ZnO NS as active semiconducting elements in flexible electronic circuits.
