Structural and vibrational analysis of nanocrystalline Ga1−xMnxN films deposited by reactive magnetron sputtering

Abstract: The structural and vibrational properties of nanocrystalline Ga 1−x Mn x N films deposited by reactive magnetron sputtering were analyzed in a wide composition range ͑0 Ͻ x Ͻ 0.18͒. The films were structurally characterized using x-ray diffraction with Rietveld refinement. The corresponding vibrational properties were investigated using micro-Raman and Fourier transform infrared spectroscopies. The films present a high crystallized fraction, crystallites having wurtzite structure, and high orientation texture … Show more

“…21 A fase termodinamicamente mais estável do GaN é a fase hexagonal do tipo wurtzita (B4), 49 grupo espacial P6 3 cm, 50 no qual cada átomo de Ga se encontra no centro de um tetraedro distorcido coordenado a quatro outros nitrogênios vizinhos. Esta estrutura possui dois parâmetros de rede externos a (plano basal) e c (plano uniaxial) e uma coordenada interna u, que descreve as posições relativas do ânion e do cátion ao longo do eixo z, Figura 1.…”

“…In this work, the average value obtained by the four functionals was 1.96–1.97 Å. As for nanocrystalline GaN films produced by sputtering, the values ​​1.93 and 2.07 Å were found for the bonds of the base and along [0001] direction, respectively, the average being 1.97 Å . The average results, with low standard deviation, for a set of 14 experimental results for crystalline samples nominally strain‐free by Moram and Vickers indicates a BL average of 1.95 Å.…”
