Superconductivity in monolayer Ba2N electride: First-principles study

Transition from semiconductor to conductor of a Mg2N electride induced by strain

“…4(b)). Based on the McMillan-Allen-Dynes formula, the calculated superconducting T c of Mg 2 N is about 0.3 K. From previous studies, some other monolayer electride superconductors Ca 2 N and Ba 2 N have also been proposed with the respective of 4.7 and 3.4 K, 43,44 which are higher than that of Mg 2 N. So, our calculation result on the superconductivity of Mg 2 N is reasonable. Fig.…”

Periodic trends in the structural, electronic, and transport properties of electrenes

“…However, only a handful of studies have discussed the electronic structure of the Ba-based sub-pnictides in low-dimensional form. 11,42,50,51 Moreover, little is known about the transport properties of these materials, with only Ca 2 N and Sr 2 N having been analyzed theoretically. 52,53…”

Unconventional stoichiometric two-dimensional potassium nitrides with anion-driven metallicity and superconductivity

“…The present T c value is comparable to 0.86 K for 1T-TaN 2 , 80 1.3 K for 1H-TaN 2 , 80 and 3.4 K for Ba 2 N monolayer. 81…”
