Nanosecond spin lifetimes in bottom-up fabricated bilayer graphene spin-valves with atomic layer deposited Al${}_2$O${}_3$ spin injection and detection barriers

Marc Drögeler, Frank Volmer, Maik Wolter +5

We present spin transport studies on bi- and trilayer graphene non-local spin-valves which have been fabricated by a bottom-up fabrication method. By this technique, spin injection…
