Influence of structure changes of oxide films on their physical properties

Structural, electrical, and optical properties of reactively sputtered SnO2 thin films

“…It is possible that nano-structured Sn metal or other secondary phases may exist in the amorphous films, providing the higher conductivity [20][21][22]. Although further investigation of the Sn nano-structure is necessary, in this paper we will discuss the microstructure of the films based on XRD measurements.…”

Investigation of properties of thin oxide films SnOx annealed in various atmospheres

“…The following annealing at temperatures higher than the melting point of tin leads to the decay of h-Sn crystal grains in the film volume. Tin excess is segregated on the film -substrate boundary as h-Sn large aggregates, which are isolated from each other by crystal grains of SnO [11]. The increase of film resistance [11] and transparence [12] at these temperatures are observed.…”

“…In papers [11,12] a relation of electrical and optical properties of films with segregation of tin was shown. After deposition and heat treatment [11] or plasma treatment [12] at temperatures lower than the melting point of tin (231.9 -C) the formation of h-Sn crystal grains in the film volume was observed. As a consequence of this, the decrease of film resistance [11] and transparence [12] had been observed.…”

Coupled Semiconductor Metal Oxide Nanocomposites: Types, Synthesis Conditions and Properties

“…Due to the fact that Sn(II) is easily oxidized to Sn(IV) , production of SnO/ZnO coupled nano oxide is relatively difficult. Thus, very few articles have been reported on the synthesizing of tin monoxide (SnO) [22][23][24][25][26][27][28] and to authors' best knowledge, no article on the synthesis of SnO/ZnO nanosized coupled oxide has been published till date. In this section, fabrication of SnO/ZnO nanosized coupled oxide with oxidation state of II for tin in solution by using the simple method of co-precipitation is reported.…”
