Optical and electrical properties of p-type transparent conducting CuAlO2 thin film

Structural, optical and electrical properties of Mg-doped CuCrO2 thin films by sol–gel processing

“…Thus far, several Cu-base delafossites have been reported such as CuFeO 2 [11], CuGaO 2 [12], CuInO 2 [13], CuScO 2 [14], CuCrO 2 [15][16][17] and Mg-doped CuCrO 2 and so on [18][19][20][21][22]. As we all known, most delafossite films were prepared by pulsed laser deposition (PLD) [23], sputtering [24], electron beam evaporation [25] and chemical vapor deposition (CVD) [26,27] and so on. There are fewer reports on the sol-gel synthesis of delafossite thin films [28][29][30].…”

Effect of substrate temperature on the physical properties of dc magnetron sputtered CuAlO2 films

“…Combining of all these properties, CuAlO 2 becomes an important material in the last few years. Several deposition techniques such as pulsed laser deposition [3,4], chemical vapor deposition [13,14], dip-coating [15], spin-on technique [16], ion exchange [17], polymer-assisted deposition [18], sputtering [19][20][21], and electron beam evaporation [22] were employed for the preparation of CuAlO 2 films. Among these techniques, direct current (dc) magnetron sputtering is one of the best technique for the preparation of films on large area substrates with required chemical composition at low substrate temperatures.…”

Theoretical Study of Electronic Structure and Thermoelectric Properties of Doped CuAlO2

“…5 However, these are smaller than the values for the experimental optical gap, which are 3.61 eV 21 and 3.96 eV to 4.20 eV. 22 It is well known that first-principles calculations underestimate energy gaps in comparison with experimental values. Therefore, these calculations should include the GW approximation, 23 B3LYP, 24 LDA plus U, 25 screened exchange (sX), 26 and weighted density approximation (WDA) 27 in order to obtain accurate E g values from the calculations.…”
