“…The literature survey shows that as deposited cadmium stannate films are amorphous in many experiments. By annealing these films at different temperatures in vacuum or in the atmosphere of various gases or mixture of gases polycrystalline films were obtained [1][2][3]5,7,[11][12][13][14][15][16]19,23]. In the present work as deposited films prepared at 500°C confirm the formation of Cd 2 SnO 4 thin films when compared with the corresponding XRD of the JCPDS data [31].…”

“…Cd 2 SnO 4 is an n-type semiconductor [1] and have great technological interest due to their high quality electrical and optical properties superior to the conventional transparent conducting oxide materials [2,3]. In addition, these films have wide applications in photogalvanic cells [4], liquid crystal displays [5], heat mirrors [6], transparent electrode [7] and solar cells [8][9][10]. Recently it has been reported that, Cd 2 SnO 4 thin films have several significant advantages in the CdTe/CdS based solar cells.…”

“…Thus preparing the low cost and quality cadmium stannate thin films is an important and useful task. Various deposition methods such as rf sputtering [1,2,6,7,[11][12][13][14][15][16][17], DC reactive sputtering [18][19][20][21], DC magnetron plasmatron sputtering [5], reactive magnetron sputtering [22] and atom beam sputtering [23] were employed to prepare cadmium stannate films. Spray pyrolysis technique was employed to prepare cadmium stannate films using CdCl 2 as precursor materials [24,[25][26][27][28].…”

“…If we assume that the conducting carriers originate entirely from the doubly charged oxygen (here taking Z to be 2), the x should be lower than that if we assume the conducting carriers only originate from tin dopant, in order to fit the simulation well with the experimental data. Furthermore, the strong dependence of the electric properties of the TCO films on oxygen has been observed in the preparation of almost all TCO films such as In 2 O 3 [69], In 2 O 3 :Sn (ITO) [54,70], ZnO:Al (ZAO) [58], SnO 2 :F, SnO 2 :Sb [71] and Cd 2 SnO 4 (CTO) [72]. All these results indicate the existence of a narrow oxygen window for low-resistivity/high-transparency TCO films and the oxygen is critical for the deposition of high-quality TCO films.…”

Contributions of acoustical deformation scattering, ion impurity scattering and grain boundary potential scattering to the conductivity of TCO films have been calculated in order to deduce the intrinsic limit of conductivity of TCO films regardless of precise details of the preparation procedure. The results indicate that the effective mass of charge carriers has a strong dependence on carrier concentration. Based on the effective mass correction, as well as the carrier concentration ionized impurity centre correction, scattering due to ion impurity has been developed to explain the upper limit of mobility or the lower limit of resistivity of TCO films. Two empirical expressions are introduced to depict the dependence of the upper limit of mobility and the lower limit of resistivity of TCO films on carrier concentration. The dependence of transparency on carrier concentration is also discussed.

“…14 Because of their optical and electrical characteristics, CTO films are good candidates as transparent conductive electrodes in CdS/CdTe and CdS/CIGS type solar cells. Therefore CTO films may find applications in photovoltaic cells 8,9,14,21,22 liquid crystal displays 23 and heat mirrors. 24 Recent studies show that cadmium tin oxide thin films can be used also in development of unconventional radiation dosimeters.…”

Cadmium tin oxide (CTO) films on glass substrates were synthesized and functionalized by octadecyltrichlorosilane (OTS). CTO films were transparent with the bandgap of 2.92 eV. They exhibited n-type conductivity and carrier concentration of (3.31 ± 0.38) · 1019 cm−3. Weak temperature dependence points out to a nearly degenerative state of the carriers in the CTO films. Silanization by OTS yielded hydrophobic surface with the contact angle values reaching 103 ± 12 degrees. Silanization of films was followed by a significant reduction of the interfacial capacitance, which upon completion of the functionalization reached levels below 3 μF cm−2. The value of the electric capacitance as well as data of ATIR absorption, hints at sparse and disordered coverage of the CTO surface by octadecylalkylsilane molecules. Such organic layer, however, was able to trigger phospholipid (60% dioleoylphosphocholine and 40% cholesterol) vesicle rupture and the formation of a secondary layer of phospholipid, thus rendering hybrid bilayer surface construct. Such hybrid constructs may be useful in applications where electrode coupling to a model biological membranes and membrane bound proteins is required, such as biosensing and photovoltaics.
