GDOES – Briefly Explained
Simplified Operating Principle
As the electrons gain kinetic energy, they release it through inelastic collisions with argon atoms, resulting in ionization of the argon atoms and the formation of argon cations and free electrons. This avalanche effect increases the density of charge carriers, transforming the insulating argon gas into a conductive state and forming a plasma—a mixture of neutral gas atoms and free charge carriers.
The argon cations are driven towards the sample surface due to the high negative potential present there. Upon impact with the sample surface, the argon cations transfer their kinetic energy to the atoms on the surface, causing them to be dislodged from the sample. This phenomenon is known as cathode sputtering or simply sputtering. The degradation of the sample surface occurs in a plane-parallel manner.
