Theoretical treatment for the ion sputtering process from quantum dot surface

الملخص EN

In this study, simple theoretical treatment is presented to calculate the neutralization and excitation probabilities throughout the ground state channel and the throughout the excited state channel for atom sputtered from quantum dot surface.

The system energy levels considered in our treatment are just the levels lying within the energy window.

The Hamiltonian that describes the system is written taking into account the ground and the excited states of the sputtered atom as well as the electron scattering process (i.e.

the electronic excitation) within the quantum dot energy band levels.

We get use of Heisenberg equations of motion to derive the equations of motion that describe the system.

The law of charge conservation is investigated.

The set of related equations are solved numerically.

The effect of electronic excitation within the quantum dot band energy is highlighted and disscused.
