Ab Initio Study on Dopant Relaxation Mechanism in Ti and Ce Cationically Substituted in Wurtzite Gallium Nitride

“…The substitutional incorporation of the dopant ions is capable of changing electronic structure, catalytic activity, light absorption or transmission, luminescence, and introducing magnetic properties to the materials [ 3 ]. Doping of foreign atoms into elemental and compound hosts is carried out either during synthesis or after growth via different methods [ 4 ].…”

“…In order to computationally model the process, the placement of the dopants at lattice sites is usually simulated via first-principles methods. The rich literature in this regard points to the strategy of inserting the foreign atoms in the host followed by geometry optimization which usually relaxes the structure to settle the dopant either precisely on cationic lattice sites or in proximate locations [ 3 , 4 , 5 , 6 ]. The properties of the doped materials strongly depend upon the dopant’s location in the host due to which placement of the dopants should be carefully handled [ 7 ].…”

La3+and F−dual‐doped multifunctional hydroxyapatite nanoparticles: Synthesis and characterization

“…The production and characterization of new materials that can meet the physicochemical, mechanical, and biochemical needs of human body parts by doping dual ions to the hydroxyapatite structure are among the studies that are frequently performed. St and Er (Mahmood et al, 2020), Tb and Gd (Liu et al, 2014), Fe and Se (Alshemary, Engin Pazarceviren, Tezcaner, & Evis, 2018), St and Mn (Huang et al, 2016), Eu and Gd (Chen et al, 2011), Co and Mg (Kulanthaivel et al, 2015), Ce and Sm (Kaygili et al, 2021) ions were doped in HA structure to investigated the effect on the structural, mechanical, magnetic, and luminescence properties of HA. Also in these studies were aimed to produce materials with improved biological and physicochemical properties by investigating bioactivity, osteogenesis, and angiogenic processes (Aina et al, 2012; Cacciotti, 2019; Chen et al, 2011; Evis & Webster, 2011; Hidouri, Dorozhkin, & Albeladi, 2019; Kulanthaivel et al, 2015; Mansour, El‐Dek, Dorozhkin, & Ahmed, 2017; Safarzadeh et al, 2019; Stanić et al, 2010).…”
