Synthesis and characterisation of co-evaporated tin sulphide thin films

Tin sulphide films were grown at different substrate temperatures by a thermal co-evaporation technique. The crystallinity of the films was evaluated from X-ray diffraction studies. Single-phase SnS films showed a strong (040) orientation with an orthorhombic crystal structure and a grain size of 0.12m. The films showe...

Temperature-dependent structural and optical properties of SnS films

The structural and optical properties of SnS films deposited on glass substrates have been studied at different temperatures under a vacuum of 10 6 Torr 10 6 Torr . At room temperature, the SnS films showed orthorhombic crystal structure with lattice parameters of a = 0.424 a = 0.424 , b = 1.107 b = 1.107 , and c = 0.3...

Influence of annealing on physical properties of evaporated SnS films

The effect of annealing on the composition, crystal structure, surface features and electro-optical properties of tin mono-sulfide (SnS) films, deposited by thermal evaporation at 300 C, has been studied. Elemental analysis of the films shows sulfur deficiency, which increases at higher annealing temperatures ( T a ). ...

Low Resistive Micrometer-Thick SnS : Ag Films for Optoelectronic Applications

Ag-doped SnS SnS films have been grown with a thickness of 0.5 m 0.5 m by thermal evaporation technique on Coring 7059 glass substrates at a substrate temperature of 275 C 275 C . The effects of doping on the physical properties of the films have been investigated. The physical characteristics of the films are discusse...

Knocking Down Highly-Ordered Large-Scale Nanowire Arrays

The large-scale assembly of nanowire elements with controlled and uniform orientation and density at spatially well-defined locations on solid substrates presents one of the most significant challenges facing their integration in real-world electronic applications. Here, we present the universal knocking-down approach,...
