Abstract Scope |
Previous studies have reported on gamma irradiation for mechanically exfoliated, chemical vapor deposition (CVD), and epitaxial grown 2D materials-based devices. However, radiation effects of printed 2D materials have yet to be reported. This work investigates the roles of microstructure and the substrate properties affected by gamma irradiation in aerosol-jet printed (AJP) 2D materials.
Radiation effects from Cobalt-60 gamma-ray are reported for aerosol-jet printed 2D-materials (graphene, MoS2, WS2, and h-BN) on various substrates (Si/SiO2, glass, sapphire, and Kapton). Irradiated samples are characterized through Raman spectroscopy, SEM/EDX, Keyence, XPS, and stylus profilometer. Preliminary electrical characterization on printed h-BN capacitors before and after gamma radiation have also been conducted. The results display negligible changes in their properties suggesting potential suitability for space applications. The information gained from this study is expected to provide new fundamental insights that can guide the development of nuclear and space applications of printed 2D material devices. |
