LEEM movie showing
self assembly
of Pb overlayer domains on Pb/Cu surface alloy. The field of view is 4
microns. The sequence lasts 25 minutes in real time. |
|
LEEM Movie showing
step faceting
and stripe formation on the (001) surface of heavily boron-doped
silicon.
The field of view is 9 microns. |
|
LEEM movie showing the formation
of a froth
phase for the system of Pb/Cu(111). The field of view is 3
microns.
The sequence lasts 2 hours, 14 minutes in real time. |
|
LEEM Movie showing the Si(111)
7x7 to1x1 phase
transition. The temperature is cycled trhough the transition
several
times. The field of view is 2.8 microns. |

| LEEM images showing self assembly of Pb overlayer domains on a Pb/Cu surface alloy. The field of view is 2.7 microns. The patterns evolve from circular islands of the overlayer phase (droplets) to a labyrinth-like pattern (stripes) to circular islands of the surface alloy phase (inverted droplets). | |
 |
LEEM images showing various metastable patterns of Pb overlayer domains on a Pb/Cu surface alloy. The field of view is 3 microns. |

LEEM images of Si(100) surfaces. The left and center images are from a highly boron doped sample during cooling from 1000 C to 900 C. The right image is what you see after working too hard. The fields of view are 9 microns, 9 microns, and 4 microns. |

LEEM images of Si(111) during the 7x7 to 1x1 phase transition. Left: field of view is 2.8 microns. Right: a sequence of images showing the decay of 7x7 domains. The field of view is 2.5 microns and the temperature is 830C. |
