Growth of Large‐Scale Boron Nanowire Patterns with Identical Base‐Up Mode and In Situ Field Emission Studies of Individual Boron Nanowire

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%).
