Effects of Focusing for Atoms Sputtered from a Ni (001) Face with Angle and Energy Resolution

Аннотация

The focusing and overfocusing of atoms sputtered from Ni (001) face are studied with the use of molecular dynamics computer simulations. When a crystal transitions from the paramagnetic to the ferromagnetic state, there is a reduction in the number of focused and overfocused sputtered atoms. The evolution of distributions of sputtered atoms with the simultaneous energy and polar angle resolution due to changes in the azimuthal angle and binding energy of atoms at a surface is studied.
