Exempel på sputtering

• In summary, we can conclude that vaporization and laser beam sputtering is the main mechanisms in laser ablation, under our conditions.

• Recent work suggests that molecular sputtering of surface molecules may provide an alternative way to decelerate, without such intense heating.

• The sputtering model considered here may require significant modification for the case of highly fluffy and porous meteoroids.

• This was confirmed by the laser produced plasma ions sputtering experiments in air.

• It is seen from the diagrams that the sputtering rate at each erosion groove is changing by its length from one cathode end to another.

• These particles result from gas-phase nucleation, polymerization, or sputtering of electrode and wall surfaces.

• The particles were assumed to be slowed by sputtering, with relatively low sputtering coefficient of 0.5.

• Synthesis of nanocrystalline material by sputtering and laser ablation at low temperatures.

• This results in a lack of reliable data on the sputtering yield under operational conditions.

• It is not acceptable for cleaning since the cathode sputtering is sufficient in argon atmosphere in this case.

• Sputtering provides a mechanism for the meteoroids to lose a substantial fraction of their momentum and energy without experiencing extreme heating.

• A high-density and low-temperature divertor means lower plate sputtering.

• Other sputtering processes may be considered in the future.

• The actual situation in respect of sputtering is contingent on several factors, such as particle size, composition, shape and porosity, that remain uncertain.

• Resistance to motion of a small, hypervelocity sphere, sputtering through a gas.
