摘要:

在1 T-TiSe 2上进行了几个实验,以确定电子结构是半金属还是半导体,但没有达成共识。本文从理论上研究了电子-空穴和电子-声子关联对裸半金属和半导体电子结构的影响。由此产生的电子光谱功能提供了一个直接的比较,这两种情况下,并表明,1 T-TiSe 2是主要的半导体字符与一些光谱权重交叉费米能级。

英文摘要:

Several experiments have been performed on 1T-TiSe2 in order to identify whether the electronic structure is semimetallic or semiconducting without reaching a consensus. In this paper, we theoretically study the impact of electron-hole and electron-phonon correlations on the bare semimetallic and semiconducting electronic structure. The resulting electron spectral functions provide a direct comparison of both cases and demonstrate that 1T-TiSe2 is of predominant semiconducting character with some spectral weight crossing the Fermi level.
