Transport evidence of the three-dimensional Dirac semimetal phase in doped $\alpha$-Sn grown by molecular beam epitaxy

Yuanfeng Ding, Bingxin Li, Chen Li +3

We report the quantum transport properties of the $\alpha$-Sn films grown on CdTe (001) substrates by molecular beam epitaxy. The $\alpha$-Sn films are doped with phosphorus to tune the Ferm…
