Efficiently gate-tunable ferromagnetism in ferromagnetic semiconductor-Dirac semimetal p-n heterojunctions

Emma Steinebronn, Saurav Islam, Abhinava Chatterjee +15

We use molecular beam epitaxy to develop a gate tunable p-n heterojunction that interfaces a canonical Dirac semimetal, Cd${}_3$As${}_2$, and a ferromagnetic semiconductor, In${}_{1-x}$M…
