Boron nanowires (BNWs) are considered as an ideal optoelectronic nanomaterial , but controlling them in identical growth mode and large‐area patterns is technically challenging. Here, large‐scale BNW patterns with a uniform base‐up growth mode are successfully fabricated by choosing Ni film as the catalyst. Moreover, they exhibit low turn‐on field (4.3 V/μm) and excellent field emission uniformity (88%).
