Symposium ES4—Nanogenerators and Piezotronics

Scavenging ambient energy into electricity by nanogenerators offers a unique approach for powering electronics and sensors system. The integration of nanogenerators, energy storage units and functional devices has led to the implementation of self-powered systems for various emerging applications in implantable electronics, nanorobotics, and wearable devices. The coupling between piezoelectric polarization and semiconductor properties in piezoelectric semiconductors gives rise to unprecedented device characteristics. This has increased research interest in the emerging fields of piezotronics and piezo-phototronics, which offer new means of manipulating charge-carrier processes in flexible devices through the application of external mechanical stimuli. This symposium aims to advance fundamental understandings and technological development of nanogenerators and piezotronics/piezo-phototronics. Abstracts on theoretical and experimental study of piezoelectric, ferroelectric and dielectric nanomaterials; applications of nanogenerators for self-powered devices; fundamental coupling between piezoelectric/ferroelectric polarization and semiconductor properties in 1D/2D nanomaterials and their applications are particularly welcome.
