Using gravure- and/or inkjet-printing techniques to realize uniform ZnO nanoparticles-based seed layers

Zinc oxide (ZnO) nanowires (NWs) are excellent candidates for the fabrication of energy harvesters, mechanical sensors, piezotronic and piezo-phototronic devices thanks to the interplay between piezoelectric and semiconducting properties. The growth of ZnO NWs on flexible substrates would further broaden their possible applications. However, such a growth requires low temperature synthesis to prevent any damage…

New range of light driven devices

The recent progresses made in the manufacturing of new plasmonic photomobile films are offering an innovative solution for light induced motion actuators and devices. Indeed, such films can be assimilated as transducers thanks to their ability to convert light into displacement with strokes up to several millimetres. By adjusting the incident light parameters (wavelength, exposure…

A new strategy to improve the measurements and analysis at the nanoscale using Piezoresponse Force Microscopy in PULSE-COM project

Piezoelectric and semiconducting zinc oxide (ZnO) nanowires (NWs) are excellent candidates for the fabrication of energy harvesters, mechanical sensors, piezotronic and piezophototronic devices [1]. Understanding the interplay between piezoelectricity and semiconductor physics is fundamental to enhancing the performance of these devices. Within PULSE-COM we explored the piezoelectric performance of vertically grown ZnO NWs based on…
