“…In recent years, many techniques have been adopted for the synthesis of Cd 2 SnO 4 materials, such as sputtering, spray pyrolysis, the sol-gel method, co-precipitation, the thermal combustion method, and the hydrothermal method. [8][9][10] Although the basic transport mechanisms of the carriers in the CTO films and some of the physical properties of the films have been investigated for more than 3 decades, till now, there has not yet been a clear conclusion about the carrier mobility in CTO and only a limited number of first-principles calculations based theoretical studies have been reported. Ion doping is a method to improve the optical absorption characteristics of materials by introducing different impurity ions, controlling the micro crystal structure, and changing the band structure.…”

The electronic structural, effective masses of carriers, and optical properties of pure and La-doped Cd 2 SnO 4 are calculated by using the first-principles method based on the density functional theory. Using the GGA+U method, we show that Cd 2 SnO 4 is a direct band-gap semiconductor with a band gap of 2.216 eV, the band gap decreases to 2.02 eV and the Fermi energy level moves to the conduction band after La doping. The density of states of Cd 2 SnO 4 shows that the bottom of the conduction band is composed of Cd 5s, Sn 5s, and Sn 5p orbits, the top of the valence band is composed of Cd 4d and O 2p, and the La 5d orbital is hybridized with the O 2p orbital, which plays a key role at the conduction band bottom after La doping. The effective masses at the conduction band bottom of pure and La-doped Cd 2 SnO 4 are 0.18m 0 and 0.092m 0 , respectively, which indicates that the electrical conductivity of Cd 2 SnO 4 after La doping is improved. The calculated optical properties show that the optical transmittance of La-doped Cd 2 SnO 4 is 92%, the optical absorption edge is slightly blue shifted, and the optical band gap is increased to 3.263 eV. All the results indicate that the conductivity and optical transmittance of Cd 2 SnO 4 can be improved by doping La.

“…5 The charge carrier concentration of 5 × 10 18 cm −3 was reported in this work. Later CTO thin films were deposited using: spray pyrolysis, 6,7 magnetron sputtering, [8][9][10] pulsed laser deposition, 11,12 sol-gel method, [13][14][15][16] chemical bath deposition. 17 These methods differ by their complexity and equipment necessary to produce oxide films.…”

“…One of the lowest resistivity value of 2 × 10 −3 cm and a bandgap energy value of 3.52 eV was observed for CTO crystal films annealed in vacuum. 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.…”

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.
