## Quick Questions to

### 3.3 Nucleation and Growth

| Here are some class exercises and quick questions: |  |
|  | What happens when first incoming atoms hits the surface of the substrate? Give at least 4 different possibilities. |  |
|  | Where would you expect the first imcoming atoms to be solidly bound? Use the proper terminology. |  |
|  | Define "sticking coefficient". Discuss the dependenc of the sticking coefficient for a given system on the precise substrate condition for a given substrate. |  |
|  | Explain briefly the major methods for investigations of the nucleation of thin films on substrates. |  |
|  | Explain how you get from interface energies to forces, and from forces to the wetting angle Q |
|  | Discuss and name the two major growth mode following from extreme values of Q |
|  | Discuss and name a third major growth mode |
