‘Functional materials for additive manufacturing of electronics’

by Lyudmila Turyanska, Centre for Additive Manufacturing, University of Nottingham, UK.

Abstract:

Additive manufacturing (AM) of complex multimaterial devices could provide transformative solutions for future electronics and optoelectronics [1]. We integrate nanomaterials, including metal nanoparticles, semiconductor nanocrystals and 2-dimensional materials with AM technologies for deposition of electrically conductive, optically active and dielectric layers [2-5]. We demonstrate that inkjet deposition can be used for surface functionalisation of graphene with nanomaterials such as graphene quantum dots, perovskites and lead sulphide quantum dots, for photon detection applications. By controlling the ink composition and deposition strategy we tune the spectral sensitivity of the devices from the UV-C to the near-infrared wavelength range, and achieve high photoresponsvity R > 106 A/W [4]. By co-printing different materials and utilising design freedom enabled by AM we demonstrate a fully printed graphene/perovskite photon detector [4], graphene field effect transistor [5] and multifunctional humidity, thermal, and pressure sensor. Our work highlights the opportunities for scalable manufacturing of optoelectonic devices and sensors based on low dimensional materials.
