Abstract
The superlattice 2D structures investigated were produced using multiple drawing technique from the tubes prepared from optical glass. For air-glass structures the stacks containing some dozens of cylindrical hollow tubes forming hexagonal structure placed in the glass envelope was used. Then these stacks were packed together, redrawn and so on. Resulting structures had a pitch 10…0.2 microns. The example of the structure is shown in Fig. 1, demonstrating 2 first—levels of superlattice. For metal glass structure we use stacks made from 10×10 glass tubes filled with low-temperature melted metal (Pb-Sn mixture). The microphotograph of this structure is shown in Fig. 2. After 3 or 4 drawing the structures produced have the pitch from 30 to 0.05 microns with the nanowires diameter up to 30 nm.
