Mobility of single vacancies and adatoms in graphene at room temperature
Tuan T. Tran, Per O. Å. Persson, Ngan Pham +2
We investigate the mobility of structural defects, adatoms, and defect-adatom combinations in self-supporting graphene subjected to keV ion irradiation. In the first scenario, homo…

The influence of geometry and specific electronic and nuclear energy deposition on ion-stimulated desorption from thin self-supporting membranes
Radek Holeňák, Michaela Malatinová, Eleni Ntemou +2
We investigate the dependence of the yield of positive secondary ions created upon impact of primary He, B and Ne ions on geometry and electronic and nuclear energy deposition by t…

Local electronic excitations by slow light ions in tungsten
Evgeniia Ponomareva, Eduardo Pitthan, Radek Holeňák +4
Accurately predicting the electronic energy deposition of ions in materials is an important challenge in both fundamental and applied research. While employing ab initio simulation…
