“…We also find that treating d electrons as part of the valence is essential for obtaining the correct energetic ordering for the phases of Ga 2 O 3 (monoclinic being lower in energy than corundum). We attribute the importance of Ga 3d states to the fact that they are close in energy to the O s states; the resulting hybridization impacts the energetics, as also observed by Sabino et al 26 Our calculated j values along three crystallographic directions are shown in Fig. 1 The thermal conductivity of bulk b-Ga 2 O 3 has previously been investigated theoretically by Santia et al 25 and also in several experiments.…”

“…This result matches the earlier studies in which they have also shown that the formation energy has the tendency of β<ε<α during the Ga2O3 synthesizing process which indicates that β-phases Ga2O3 should be the primary product after processing. 34,35,36 Then, we gradually doped the hydrogen atoms into the material to achieve the relatively hydrogenated Ga4O6H. The relative energies were calculated and listed in Table 1 as well.…”

“…DFT têm sido largamente utilizada nos últimos anos no estudo de moléculas, 48,49 clusters, [50][51][52][53] nanoclusters, 54,55 superfícies, [56][57][58][59] e sólidos. [60][61][62][63] A proposta de representar o sistema e suas observáveis em termos da densidade eletrônica foi iniciada com o modelo proposto por Thomas-Fermi, 64 o qual possui um importante papel histórico. Porém, sua aplicação prática é comprometida por sua baixa exatidão, devido ao funcional de densidade eletrônica para a energia cinética se basear na 3 A massa do elétron é, no mínimo, 1836 vezes menor que a do núcleo.…”
