摘要： This paper is devoted to the investigation the fermion tunneling radiation of squashed black holes in the Gödel universe and charged Kaluza--Klein space--time. For black holes with different dimensions, establishing a set of appropriate matrices γμ for the general covariant Dirac equation plays an important role in the semi-classical tunneling method. By constructing two sets of γμ matrices, we have successfully derived the tunneling probability and Hawking temperature of the black holes.

Abstract: This paper is devoted to the investigation the fermion tunneling radiation of squashed black holes in the Gödel universe and charged Kaluza–Klein space–time. For black holes with different dimensions, establishing a set of appropriate matrices $\gamma^{\mu}$ for the general covariant Dirac equation plays an important role in the semi-classical tunneling method. By constructing two sets of $\gamma^{\mu}$ matrices, we have successfully derived the tunneling probability and Hawking temperature of the black holes.
