1. Random deposition of particles:
simulation of the real world

3. Snow particles falling on a window

4. Ag on Pt at 110K

5. Use computer simulation to find out the hidden rules behind the growth

6. Ballistic deposition

7. L=200
35000 particles
<h(t)> ~ t

8. Surface roughness v.s. time
Saturation
of the width
Cross-over

9. Both the cross-over time and the surface roughness depends on system size L

10. With proper units of length and time, all the curves can be “collapsed” to the same curve

12. 2-dim growth
Diffusion-limited aggregation
