Abstract:
Technological regimes of vapor-phase transport (VPT) synthesis of filamentous nanocrystals (nanowhiskers) of tin oxide (SnO$_2$) are considered. It is experimentally established that the morphology of VPT-grown SnO$_2$ nanocrystals depends on the initial charge composition, carrier gas, and degree of vapor phase supersaturation in the growth zone. The VPT synthesis has been successfully used to obtain fractal volume single crystals, nanofilaments, and nanowhiskers with diameters ranging from 50 to 1000 nm.
