Molecular Simulation Studies of Scattered and Penetrated Hydrogen Ions I. Normal Incident Angle to Ni (100) Surface

산란 및 투과된 수소 이온의 분자 전산 연구 I. 니켈 (100) 표면의 직각 입사

Molecular dynamics simulations have been carried out to investigate the scattering and penetration properties of hydrogen ions with the normal incident angle to Ni (100) surface. The initial kinetic energies of hydrogen ions range from 100 to 1,600 eV. The simulation results are used to assess the applicabilities of theoretical predictions based on the binary collision approximation, and, in the high kinetic regime, theoretical results for scattering energies were shown to he a good agreement with molecular simulations. The angle dependencies on both scattering and penetration distributions were found in the longitudinal direction, but not in the azimuthal direction except for the high kinetic energy of 1,600 eV.
