“…The formation energy depends on the growth conditions, which may vary between N‐rich and Ga‐rich. The formation energy equation of the doping model under N‐rich and Ga‐rich conditions is described as: [ 24–26 ]

\begin{matrix} E_{normalf} = E_{TM - doped} - E_{pure} + n μ_{Ga} - n μ_{TM} \end{matrix}

\begin{matrix} E_{normalf} = E_{TM - doped} - E_{pure} + n μ_{normalN} - n μ_{TM} \end{matrix}

In order to make GaN nanowires better used in the field of spin‐polarized electron sources, the structure and properties of transition metal (Cr, Mn, Fe, Co, and Ni) particles doped nanowires are studied through first principles. The research results show that transition metal (TM) particles are more likely to be doped on the outermost surface of GaN nanowires. The work function of Cr‐doped GaN nanowires has the largest decrease, which is 2.06 eV. For TM‐doped nanowires, magnetic moments are induced, which are mainly derived from the polarization of 3d electrons of TM atoms and 2p electrons of N atoms. Mn‐doped GaN nanowires with 100% spin polarization characteristics seem to be good candidates for spin‐polarized electron source photocathode applications.

“…[18] Although only perovskite structures were found by x-ray diffraction, the nominal La 0.7 Sr 0.3 MnO 3 samples synthesized below 1200 • C comprise at least two magnetic phases. Single magnetic phase can only be achieved in the samples synthesized above 1200 • C. [19] The observed magnetic phase separation should be caused by the miscibility gap between LaMnO 3 and SrMnO 3 . Therefore, the magnetic phase separation may affect the lattice structure and consequently contribute to the wettability of La 0.7 Sr 0.3 MnO 3 coatings.…”

As proposed by Herminghaus, a hierarchical structure could render any surface nonwettable as long as the roughness amplitude at small scales is sufficient to suspend a free liquid surface. Recently we reported that the wettability of La0.7Sr0.3MnO3, an intrinsic hydrophilic oxide, can be tuned from superhydrophilicity to superhydrophobicity by hierarchical microstructures generated by annealing the coatings of La0.7Sr0.3MnO3 powder in nanometric scale at different temperatures. Here we further demonstrate the similar phenomenon observed on LaMnO3 coatings, which conforms THAT the surface geometrical structure is a key factor to determine the wettability.
