Xe irradiation of graphene on Ir(111): From trapping to blistering
Xe irradiation of graphene on Ir(111): From trapping to blistering
Using x-ray photoelectron spectroscopy, thermal desorption spectroscopy, and scanning tunneling microscopy, we show that upon keV ${\mathrm{Xe}}^{+}$ irradiation of graphene on Ir(111), Xe atoms are trapped under the graphene. Upon annealing, aggregation of Xe leads to graphene bulges and blisters. The efficient trapping is an unexpected and remarkable phenomenon given …
