Radiation treatment of Cd 2 SnO 4 thin films prepared by RF sputtering with different preparation conditions

Cd2SnO4 transparent conductive oxide: a promising alternative candidate for highly efficient hybrid halide perovskite solar cells

“…21 The conduction band edge position is closely matched with the conduction band minimum of TiO 2 . The structure and optical characteristics of cadmium stannate thin lms can be further tailored by gamma irradiation 21 and suitable dopants, such as In and Sb. 22 Furthermore, Cd 2 SnO 4 thin lms require costeffective preparation techniques including radio frequency magnetron sputtering, 23 sol-gel, 24 dip coating, 25 and spray pyrolysis.…”

“…[18][19][20] The thin lm has demonstrated an electron mobility and resistivity of up to 100 cm 2 V À1 s À1 and 1.28 Â 10 À4 U cm, respectively. 19,21 It is a n-type semiconductor material with a band gap of around 3.0 eV, in which oxygen vacancies act as donor states. 21 The conduction band edge position is closely matched with the conduction band minimum of TiO 2 .…”

Improved electrical and optical properties in epitaxial Cd2SnO4 films

“…12 Among the ternary compounds, cadmium stannate (Cd 2 SnO 4 ) is an n-type semiconductor with an orthorhombic structure and an optical bandgap of approximately 3.0 eV. 13 This material possesses excellent thermal stability as well as strong ionic properties, which make it significant for many applications including the liquid crystal display smart windows, transparent electrodes, and photovoltaic generators. [14][15][16] So far, a variety of chemical and physical techniques, including spray pyrolysis method, 17 radio frequency magnetron sputtering technique, 18 and dip coating, 19 have been used to fabricate the Cd 2 SnO 4 films; however, only the polycrystalline structures of the Cd 2 SnO 4 thin films were observed via these techniques.…”

Oxygen vacancy and doping atom effect on electronic structure and optical properties of Cd2SnO4

“…7 A variety of methods for preparing the Cd 2 SnO 4 lm were then attempted, including chemical vapor deposition (CVD) method, 8 pulsed laser deposition (PLD) method, 9 spray pyrolysis method, 10 sol-gel method, 11,12 electron beam evaporation method, 13 DC sputtering [14][15][16][17] and RF sputtering. [18][19][20][21] In many of the preparation methods, the CTO lms prepared by magnetron sputtering had the lowest resistivity, and the resistivity of lms prepared by various magnetron sputtering methods was much lower compared with other methods. In all experiments using magnetron sputtering to deposit CTO thin lms, we found that most of the deposited lms were heat treated, [22][23][24] and when the deposition atmosphere contained oxygen, the CTO lm can be a low resistance lm aer heat treatment.…”
