Cr、Mn、Fe掺杂AlN晶体的电子性质

Electronic properties of AlN crystal doped with Cr, Mn and Fe

S. V. Syrotyuk, V. M. Shved

摘要:

用ABINIT程序计算了掺Cr、Mn和Fe的AlN晶体的自旋分辨电子能带谱以及部分和总电子态密度。关联电子的Hartree-Fock交换被用来描述PAW框架中的关联轨道。计算出的自旋向上和向下的电子的单电子能量是非常不同的。我们已经发现,所有考虑的晶体是铁磁性的。

英文摘要:

The spin-resolved electronic energy band spectra, as well as partial and total density of electronic states of the crystal AlN, doped with Cr, Mn and Fe, have been evaluated within the projector augmented waves (PAW) approach by means of the ABINIT code. The Hartree-Fock exchange for correlated electrons is used to describe the correlated orbitals in the PAW framework. The calculated one-electron energies for electrons of spin up and down are very different. We have found that all the considered crystals are ferromagnetic.
