“…Delafossite type oxides Cu I M III O 2 with M = (Fe, Al, Ga, Cr…) due to their large range of properties and the abundance of their constituent elements in the nature, have been studied for several applications such as transparent p-type conducting oxides (TCO) [10,11,12,13,14,15,16,17], transparent electronic devices [18,19,20,21,22,23,24,25], dye-sensitized solar cells [26,27,28,29], and photoelectrodes [30] but also for outstanding catalysis [31] and photo-catalysis [31,32,33,34,35,36,37,38,39,40,41], antibacterial [42], luminescence [43,44,45], gas and temperature sensing [46,47,48,49], magnetic and electric [50,51,52,53,54], energy storage [55], oxygen storage [56], water reduction [57], thermoelectricity and superconductivity [58] properties. In the oxide family, the cation Cu I is a monovalent metal and the cation M III is a trivalent metal.…”

P-type Mg doped CuCrO2 thin films have been deposited on fused silica substrates by Radio-Frequency (RF) magnetron sputtering. The as-deposited CuCrO2:Mg thin films have been annealed at different temperatures (from 450 to 650 °C) under primary vacuum to obtain the delafossite phase. The annealed samples exhibit 3R delafossite structure. Electrical conductivity σ and Seebeck coefficient S of all annealed films have been measured from 40 to 220 °C. The optimized properties have been obtained for CuCrO2:Mg thin film annealed at 550 °C. At a measurement temperature of 40 °C, this sample exhibited the highest electrical conductivity of 0.60 S·cm−1 with a Seebeck coefficient of +329 µV·K−1. The calculated power factor (PF = σS²) was 6 µW·m−1·K−2 at 40 °C and due to the constant Seebeck coefficient and the increasing electrical conductivity with measurement temperature, it reached 38 µW·m−1·K−2 at 220 °C. Moreover, according to measurement of the Seebeck coefficient and electrical conductivity in temperature, we confirmed that CuCrO2:Mg exhibits hopping conduction and degenerates semiconductor behavior. Carrier concentration, Fermi level, and hole effective mass have been discussed.

A review on the p-type transparent Cu–Cr–O delafossite materials

et al. 2022

Transparent conductive oxides (TCOs) constitute a class of materials that combine high electrical conductivity and optical transparency. These features led to the development of the transparent electronics applications, such as flat panel displays, “smart” windows or functional glasses. N-type TCOs dominate the applications market, and the lack of a suitable p-type counterpart limits the fabrication of a completely transparent active device, which might be considered as a technological breakthrough. Among the wide range of p-type candidates, delafossite CuCrO2 (and its out-of-stoichiometry derivatives) is a promising material to achieve the desired p-type TCO properties as, up to date, it is presenting the foremost trade-off between optical and electrical properties. The present paper covers the research work and the major achievements related to copper chromium delafossite. A comprehensive overview of fabrication methods and opto-electronic properties is presented. The source of doping and the charge carriers transport mechanism are also thoroughly discussed.

Delafossite AgFe1−xCoxO2 (x = 0, 0.05, 0.1, 0.2) powders were synthesized by co-precipitation method. The structural analysis and hyperfine interactions investigations were performed by X-ray diffraction and the Mössbauer spectroscopy. It was found that the Co-doped delafossite phase with traces of metallic silver was obtained. The investigated samples were fine powders which are typical of the materials synthesized by co-precipitation. The Mössbauer spectroscopy studies revealed random incorporation of cobalt ions into the crystalline lattice of delafossite. Doping of cobalt ions caused the distortion of the oxygen octahedra in AgFeO2 which was observed in the increase of the quadrupole splitting value.
