Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors

Morphological and Structural Evolution of Chemically Deposited Epitaxially LaNiO3 Thin Films

“…Several groups have investigated the growth of LNO on different substrates (surface aspects) by using chemical methods. (i) modified Pechini method obtained LNO thin films with rms values of about 5.4 nm and 5.3 nm crystalized at 700 and 800 °C for one layer deposition [31]. On increasing the number of layers, the rms decreases to 2.9 nm for 700 Several groups have investigated the growth of LNO on different substrates (surface aspects) by using chemical methods.…”

On increasing the number of layers, the rms decreases to 2.9 nm for 700 • C and increases to 7.8 nm for the sample annealed at 800 • C. (ii) Using the CSD method [30], for a lower scan area of 1 µm × 1 µm, the rms values of the studied samples were in the range of 2.8-5.2 nm at a temperature of 750 • C. A detailed study of the morphology evolution using different single crystalline substrates (LAO, STO, MgO, sapphire) is presented in [32].…”

Sodium citrate dihydrate doped with Mn3+ions

“…Citric acid (2-hydroxypropane-1,2,3-tricarboxylic acid) belongs to the group of polycarboxylic acids present in biological fluids and playing very important roles in biochemical processes. Complexes of citric acid also attract considerable attention in the production of special materials, such as highconductive LaNiO 3 and LaMnO 3 (Počuča et al, 2007;Ðuriš et al, 2007), using a modification of Pechini's method (Pechini, 1967;Keishi & Toshio, 2005;Petrykin & Kakihana, 2005). In spite of this, not many citrate complexes have been structurally characterized.…”
