Growth of SnO2 nanowires by thermal evaporation on Au-coated Si substrates

SnO2 dendrites–nanowires for optoelectronic and gas sensing applications

“…It is generally known that the growth process of 1D nanostructure is dominated by kinetics rather than thermodynamics. Nanoscale 1D structures of oxides prepared by thermal evaporation can be grown in either VLS or VS mechanism depending on the kind of material and the process condition [16]. The VLS mechanism is generally dominated in the thermal evaporation process carried out with the aid of a metal catalyst (Au in our case).…”

Strategies for designing metal oxide nanostructures

“…1D SnO2 nanostructures have also been reported to be synthesized via this method [95][96][97][98]. For example, large-scale SnO2 nanowires were synthesized via laser ablation [95], and SnO2 nanobelts were synthesized via thermal evaporation [96].…”

“…SnO2 nanowires with a diameter of 20 nm were deposited on Au catalysis seeded Si-SiO2 substrates [95]. Park et al [96] reported the growth of SnO2 via thermal evaporation from Au seeded Si substrates, in which the Sn vapour was generated by heating the Sn powders at 900°C in a total gas pressure of 1 Torr.…”

“…For example, large-scale SnO2 nanowires were synthesized via laser ablation [95], and SnO2 nanobelts were synthesized via thermal evaporation [96]. In the laser ablation synthesis of SnO2 nanowires, the Sn vapour is ablated by a neodymium-doped yttrium aluminium garnet (Nd:YAG) laser at 900°C and carried downstream by an oxygen-argon mixture.…”

VLS and VS effect on ferromagnetic behaviour of SnO2nanobelts

“…Diverse range of methods have been employed to attain different morphologies of SnO 2 , i.e. direct sublimation, molten salt synthesis, hydrothermal technique, template based synthesis, laser ablation, carbothermal reduction process and so on [17][18][19]. Among these methods, thermal evaporation is most popular for the synthesis of SnO 2 nanostructures.…”
