Abstract:
This study investigates the interaction of radiation with two-dimensional (2D) materials, including graphene, graphene oxide (GO), hexagonal boron nitride (hBN), and molybdenum diselenide (MoSe₂), to assess their potential in radiation sensor development. Using Monte Carlo N-Particle (MCNP5) simulations with 10⁷ to 10⁸ events, the research evaluates the materials’ responses to photons, neutrons, and charged particles, focusing on energy deposition and interaction efficiency. For photons, MoSe₂ exhibited superior interaction at low energies, while graphene showed limited absorption, particularly at higher energies. GO displayed moderate efficiency at intermediate energies, and hBN’s interaction increased with photon energy. In stacked configurations, MoSe₂ maintained high energy deposition, with other materials showing distinct low-energy behaviors. For neutrons, graphene exhibited minimal response across all energies, whereas MoSe₂ and hBN demonstrated robust interactions, especially at medium to high energies. hBN excelled in thermal neutron absorption, while MoSe₂ was more effective at higher neutron energies. Charged particle interactions mirrored these trends, with MoSe₂ leading in high-energy absorption and graphene, GO, and hBN offering balanced responses at lower energies. These findings highlight MoSe₂ and hBN as promising candidates for radiation sensors in neutron-rich and high-energy environments, while graphene and GO are better suited for moderate-energy applications, paving the way for tailored sensor designs.
