SCI Reentrant Charge Ordering Behavior in the Extended Hubbard ModelH. A. Tuan We study the charge ordering behavior in a three-dimensional extended Hubbard model using the Coherent potential approximation (CPA). It is shown that the charge ordering transition occurs due to the competition between kinetic and Coulomb energy. At various band fillings a simple reentrant behavior of the charge ordering transition is found. Tải xuống: ![]() | |||||||||
