Review on property regulation of semiconducting materials in flexible electronics

Abstract

Flexible electronics technology plays an important role in regulating the properties of semiconducting materials, leading to the breakthrough in traditional strain engineering that is limited by the rigid and brittle inorganic materials and the fixed strain values. Thereby, the relevant research not only provides a new clue for strain regulation of semiconductor materials or other functional materials, but also lays a theoretical foundation for the performance evaluation of stretchable and flexible electronic devices based on inorganic functional materials in large-deformation environments. In this paper, the research progress of flexible inorganic electronics and strain effects on band structures, especially the property regulation of semiconducting materials in flexible electronics, is reviewed. Firstly, the nano-diamond particles based thinning process and the transfer printing are emphatically expounded with their influence on the properties of semiconducting electronics explored. In addition, the development and application of strain effect on band structure in recent years are introduced. In particular, the strain control based on buckling GaAs nanoribbon and buckling quantum well structure are studied to demonstrate the superior advantage of flexible electronics technology in the property regulation of semiconducting materials. The application and developing trend of strain engineering in the future are prospected finally.
