Question

How long is the surface migration length of adatoms deposited by thermal evaporation in vacuum?

Answer 1

The deposition of metals through thermal evaporation involves the process of adatoms migrating on the substrate before its kinetic energy decreases to a certain point or before encountering a cluster.

✔️✔️the process of adatoms migrating on the substrate before its kinetic energy decreases to a certain point or before encountering a cluster.

But how long is this migration distance? At least, what order of magnitude is it in?
Condition: metal (like aluminum, gold, silver) evaporation under 10-4Pa
