- This work reveals the first microscopic evidence of an abnormal proximity effect associated with the nontrivial surface states of 3D topological insulators (TIs). TIs are promising material candidates for the next generation dissipationless electronics and topological quantum computing. However, a major obstacle is their extremely low working temperature (Tc). Our work demonstrates an unambiguously enhanced Tc of 3D TIs with exceptionally long penetration depth. It proves that proximity engineering an effective route to bring up the materials’ Tc, and potentially create new state of matters.
