Topological Dirac semimetal Na3Bi films in the ultrathin limit via alternating layer molecular beam epitaxy
Ultrathin films of Na3Bi on insulating substrates are desired for opening a bulk bandgap and generating the quantum spin Hall effect from a topological Dirac semimetal, though continuous films in the few nanometer regime have been difficult to realize. Here, we utilize alternating layer molecular be...
