Dieletric function crystalline 2H-GaS

<p>Txt files containing the dielectric function of bulk single crystal c-axis oriented 2H-GaS (gallium sulfide) both experimental and DFT calculated values.</p> <p><strong>EXPERIMENTAL</strong></p> <p><strong>GaS_bulk_experimental.txt </strong>Experimental value of the dielectric function obtain through spectroscopic ellipsometry under the isotropic assumption.</p> <p><strong>DFT CALCULATED</strong></p> <p>DFT calculations on bulk GaS were performed with SIESTA (https://siesta-project.org/siesta/). The two components of the dielectric tensor of GaS were calculated.</p> <ul> <li>in-plane component (<strong>E</strong> || <em>c</em>-axis): <strong>GaS_inplane_epsilon_img.dat</strong> and <strong>GaS_inplane_epsilon_real.dat</strong></li> <li>out-of-plane component (<strong>E</strong>&nbsp; &perp; <em>c</em>-axis): <strong>GaS_outofplane_epsilon_img.dat</strong> and <strong>GaS_outofplane_epsilon_real.dat</strong></li> </ul> <p>&nbsp;</p>
