Theoretical interpretation of the zero-field splitting parameters for Fe<sup>3+</sup> ions in wide-band gap semiconductor TlGaSe<inf>2</inf> single crystal
Abstract
<p>Superposition model (SPM) calculations are carried out to provide theoretical interpretation of the zero-field splitting (ZFS) parameters and investigate the local environment around the Fe<sup>3+</sup> centers in a TlGaSe<sub>2</sub> single crystal. Experimental electron magnetic resonance (EMR) data are analyzed and compared with the ZFS parameter values predicted by SPM based on the orthorhombic approximation of structural data. The results provide an adequate interpretation of the ZFS parameters obtained by fitting EMR spectra and indicate that Fe<sup>3+</sup> ions substitute for the Ga <sup>3+</sup> ions in TlGaSe<sub>2</sub> crystal. © 2010 Elsevier Ltd.
