materials, PbTe is distinguished as a very promising compound for power generation at intermediate-temperature range (500-900 K), successfully served in several NASA space missions [@LaLonde]. At near room temperatures (300–500 K), appropriate thermoelectric candidates are (Bi, Sb)$_2$(Se,Te)$_3$-based alloys and MgAgSb alloys, while at high temperature (&gt;900 K), half-Heusler (HH) alloys, (Pr, La)$_3$ Te$_4$, SiGe, and Yb$_{14}$ Mn Sb$_{11}$, are very promising candidates [@Xiao-npj18]. Another important thermoelectric materials are doped narrow-gap semiconductors [@Arita; @Hamada; @Zide], PbTe(1.5$~$nm)/Pb$_{0.927}$Eu$_{0.073}$Te(45 nm), multiple quantum well [@Dresselhausprb47-93-1; @Harman] and Bi$_{2}$Te$_{3}$ [@Venkatasubramanian].

Recent advances in fabrication technologies have made exploring two-dimensional materials possible for thermoelectric applications [@Wei; @Zuev; @Kato; @Buscema; @Konabe1].

As already pointed out, semi-metals with large electron-hole asymmetry can be considered as an important strategy for strong enhancement of the thermoelectric coefficients [@Markov-scr18]. Moreover, motivated by the great interest in search of thermoelectric Dirac materials, the knowledge of thermoelectric efficiency of borophane is crucial for its application in potential thermal management devices. However, to our best knowledge, answers to these question is still lacking.

In this paper, with a view to investigate the effect of various impurities on the thermoelectric performance of borophane, a Dirac semi-metals with a large electron-hole asymmetry, we perform a systematic study
