Abstract

GdN is a ferromagnetic semiconductor which has seen increasing interest in the preceding decades particularly in the areas of spin- and superconducting- based electronics. Here we report a detailed computational and optical spectroscopy study of the electronic structure of stoichiometric and nitrogen vacancy doped GdN. Based on our calculations we provide the effective mass tensor for undoped GdN, and some indicative values for electron doped GdN. Such a property is valuable as it can affect device design, and can be measured experimentally to validate the existing computation results.

GdN导带的自旋极化和非各向同性有效质量。
GdN是一种铁磁性半导体,在过去的几十年里,特别是在自旋和超导电子学领域,人们对它的兴趣越来越大。本文报道了化学计量氮空位掺杂GdN电子结构的详细计算和光谱学研究。基于我们的计算,我们给出了未掺杂GdN的有效质量张量,以及一些电子掺杂GdN的指示值。这种特性是有价值的,因为它可以影响器件设计,并且可以通过实验测量来验证现有的计算结果。

期刊介绍: Journal of Physics: Condensed Matter covers the whole of condensed matter physics including soft condensed matter and nanostructures. Papers may report experimental, theoretical and simulation studies. Note that papers must contain fundamental condensed matter science: papers reporting methods of materials preparation or properties of materials without novel condensed matter content will not be accepted.
