<div dir="ltr"><div><br></div>Dear experts,<div><br></div><div>In my calculations, I have studied four different configurations of system. Based on the calculated energy, the stable configuration (lowest value of energy) has larger Fermi energy and the highest value of energy (less stable one) is related to the lowest Fermi energy. However, I have read that increasing the Fermi energy in the system is expected to decrease the stability. I was wondering if you would help me on which parameter should be considered to determine the stability. </div><div>Thanks in advance.</div><div><br></div><div>Regards,</div><div>M.Abbasnejad </div><div><div>-- <br></div><div class="gmail_signature">---------------------------------------------------------<br><br>Mohaddeseh Abbasnejad, <br>Room No. 323, Department of Physics, <br>University of Tehran, North Karegar Ave.,<br>Tehran, P.O.
