“…Samples with doping rate x greater than 0.6 can not be obtained in crystalline form at any value of fuel ratio y. These results are in agreement with theoretical calculation by Ahmed [19], where the authors showed that the greater the doping concentration is the harder for the product can be formed due to the difference in ion radius of Ba and La. Ahmed et al calculated the dependence of formation energy of LBMO materials on doping rate.…”

The major energy sources that human are relying on are fossil fuel and it is exhausted day by day. Furthermore, exploition and usage of fossil fuel also bring in many negative impacts on environmental polution. Solid oxide fuel cell (SOFC) has been considerred as a potential solution for such environmental and energy problems. Seeking a facile, cost and time saving process to synthesize Ba doped LaMnO3 is very important for development of SOFC applications because it helps to reduce the cost of comercial SOFC. LaMnO3 doped with Ba is more cost effective than Sr doped LaMnO3 because less rare earth elements are used. At the same time, its conductivity is still good enough with an appropriate thermal expansion matched with those of other parts of SOFC based on ytrium stabilized zirconia (YSZ). In this paper, Ba doped LaMnO3 nanoparticles (LBMO), a promissing material for making cathode of SOFC, were prepared by microwave combustion method. This material has many advantages. Effect of the amount fuel in the combustion reaction on the products was studied by various methods such as: X-ray diffraction measurement, scanning electron microscopy, energy dispersive X-ray spectroscopy. The results showed that each doping rate requires an appropriate amount of fuel to obtain pure and crystalline product. The obtained LBMO nanoparticles are crystallined in hexagonal phase at doping ratio of 0.2 and orthohombic phase at doping ratio of equal or larger than 0.3.

“…This value has been optimized by other researchers. [19][20][21] The calculation was affected via the hybrid full-potential FP L/APW + lo method implemented in the Wien2k package. 22 The spin-orbit coupling effect was not included in the calculation because it had little effect in this case.…”

“…Among them, the cubic system is of special device importance. For example, cubic GaN with p-type doping of Mn, V, or Cr-doped zincblende AlP, or manganese oxides REMnO 3 (RE represents rare earth elements) of a cubic perovskite structure − show great potential for spintronic devices. Potential candidates of thermoelectric and optical devices can be cubic perovskite compound SrMnO 3 , , thermally stable cubic LaFeO 3 at high pressure, or anti-perovskite A3BX compounds (A = RE or alkaline elements, B = C, O, or N, X = main group elements) .…”

Efficiency of search of wanted materials with desired properties is limited by the huge search space. By deep learning methods, we demonstrate that space group information can be acquired from band structure inputs to reduce the search space. Despite atomic orbital or accidental degeneracies mixed with lattice degeneracies, band degeneracies as input can yield 96.0% prediction accuracy for cubic systems that leads to a 25.1-fold acceleration of searching speed overall. Additionally, for all space groups, the prediction accuracy is 82.0% with overall 36.9-fold acceleration in the search speed. In addition, valence band degeneracies as inputs can yield satisfactory results and may assist in structural analysis from ARPES results.
