| Estimate for Shape Parameter |
|
|
| Idea: Dendrite tip is geometrically-similar to the [100]-portion |
|
| of
the equilibrium shape. |
|
| For small e4
and r/z ¿ 1, the equilibrium shape is: |
| Our expansion
for the dendrite shape: |
| From the SCN anisotropy measurement: From the tip shape measurement: |
