Advanced Electronic Materials, EarlyView.This paper presented ZnO‐based crossbar RRAMs by electrohydrodynamic (EHD) printing technology under in‐space manufacture environment as microgravity (µG). The crossbar structures of Ag/ZnO/Ag are fabricated under earth with in‐space microgravity. With the microgravity effect, a significant electroforming forming voltage reduced 89.3% as a storage ...
