✦ Synopsis

Micrometer-sized three-dimensional Si cluster arrays have been synthesized at an air-water interface and a water-hydrogen-terminated Si (100) interface leveraging the hydrophobic nature of Si clusters. Structures of the arrays grown at these two different interfaces are compared. The array packing structures adopt either a b.c.c. structure with a 5 0.69 nm or an f.c.c. structure with a 5 0.75 nm at an air-water interface. Those grown on the Si substrate form two types of b.c.c. structures with a 5 0.61 and 0.69 nm. The distance between centers of adjacent Si clusters is 5.3 nm in both the b.c.c. structure with a 5 0.61 nm and the f.c.c. structure with a 5 0.75 nm. It is concluded that component clusters in the arrays grown at both types of interfaces are identical.

We have performed density functional calculations using cluster models of the C(100), Si(100) and Ge(100) surfaces. We find that the ground-state geometry is strongly dependent upon the constraints imposed during geometry optimization and also can be affected significantly by the cluster size in the
