Pulsed Laser Deposition of Crystalline Cd2SnO4 Thin Film

Abstract

Thin films of cadmium stannate (Cd2SnO4) have been deposited on glass substrates by pulsed Nd:YAG laser at room temperature. The deposited film was crystalline in nature and highly oriented in the (311) direction. Using this method, Cd2SnO4 films with the Hall mobility of 25 cm 2 V −1 s −1 and the carrier concentration of 6×10 20 cm −3 corresponding to the conductivity of 2.4×10 3 S cm −1 have been prepared without post-deposition thermal annealing. The films exhibited average optical total transmission of 70% in the visible region. The optical band gap was found to be 3.18 eV.

Cadmium Stannate Films for Immobilization of Phospholipid Bilayers

“…This effect leads to a conclusion that CTO is an n-type semiconductor consistent with previous works. 5,10,12,15,19 EIS spectra in Fig. 4A can be fitted as it was done in Ref.…”

“…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.…”

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

“…A variety of methods for preparing the Cd 2 SnO 4 film 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 14–17 and RF sputtering. 18–21 In many of the preparation methods, the CTO films prepared by magnetron sputtering had the lowest resistivity, and the resistivity of films prepared by various magnetron sputtering methods was much lower compared with other methods.…”

Mechanical and tribological properties of CdO + SnO2 thin films prepared by sol–gel

“…In particular, Cd 2 SnO 4 (CTO) deposited by sputtering has been recently tested as a TCO in a CdTe polycrystalline based thin-film solar cell with a total-area efficiency of 16.5% [3]. CTO thin films have been grown using different techniques such as spray pyrolysis [4], pulsed laser deposition [5], sputtering [6], MOCVD [7] and sol-gel [8,9]. In addition to monitoring the electric and optical properties through careful control of the processing parameters, there is a growing demand for investigating the mechanical and tribological properties of TCO films because the contact loading during processing or packaging can significantly degrade the performance of devices [1].…”
