  High-throughput density functional theory (DFT) calculations allow for a
systematic search for conventional superconductors. With the recent interest in
two-dimensional (2D) superconductors, we used a high-throughput workflow to
screen over 1,000 2D materials in the JARVIS-DFT database and performed
electron-phonon coupling calculations, using the McMillan-Allen-Dynes formula
to calculate the superconducting transition temperature ($T_c$) for 165 of
them. Of these 165 materials, we identify 34 dynamically stable structures with
transition temperatures above 5 K, including materials such as W$_2$N$_3$,
NbO$_2$, ZrBrO, TiClO, NaSn$_2$S$_4$, Mg$_2$B$_4$C$_2$ and the previously
unreported Mg$_2$B$_4$N$_2$ ($T_c$ = 21.8 K). Finally, we performed experiments
to determine the $T_c$ of selected layered superconductors (2H-NbSe$_2$,
2H-NbS$_2$, ZrSiS, FeSe) and discuss the measured results within the context of
our DFT results. We aim that the outcome of this workflow can guide future
computational and experimental studies of new and emerging 2D superconductors
by providing a roadmap of high-throughput DFT data.
