We have investigated the deterioration of field effect transistors based on two-dimensional materials due to irradiation with swift heavy ions. Devices were prepared with exfoliated single layers of MoS{sub 2} and graphene, respectively. They were characterized before and after irradiation with 1.14 GeV U{sup 28+} ions using three different fluences. By electrical characterization, atomic force microscopy, and Raman spectroscopy, we show that the irradiation leads to significant changes of structural and electrical properties. At the highest fluence of 4 Multiplication-Sign 10{sup 11} ions/cm{sup 2}, the MoS{sub 2} transistor is destroyed, while the graphene based device remains operational, albeit with an inferior performance.
