Two‐dimensional materials (2DMs) such as graphene, layered transition metal dichalcogenides, and hexagonal boron nitride have seen renewed research interest over the past decade in the search of novel nano‐scale physics and devices. These materials have been shown to be highly sensitive to their surroundings, which has revealed the importance of interface states for growth processes and device operation. This has also allowed for the development of gas and biomolecule sensors based on charge transfer to the 2DMs. In the Feature Article by R. C. Walker et al. (pp. 3065–3077 ), the focus is on the sensitivity of 2DMs to electromagnetic radiation and charged particle interactions. Such interactions are key in developing 2DMs for applications as light sensors, radiation detectors, and radiation‐hardened space electronics. Many years of developing opto‐electronics based on 2DMs have shown that they are suitable for visible and ultraviolet light detection, but more development must be done for infrared and terahertz wave detection. This review also discusses initial work in determining damage mechanisms in 2DMs due to X‐rays, gamma rays, electron beams, protons and heavy ions, and proposes future research directions.
