Abstract
The discovery of novel lightweight materials with metallic properties is important for future smart applications, and two-dimensional materials with metallic conductivity are quite rare in this regard. Herein, we report an electrically conductive two-dimensional hydrogen boride material (borophane) that was synthesized in powder form by an ion-exchange reaction. The produced freestanding borophane was amorphous by X-ray diffractometry and found to consist of curved layers of elongated hexagonal networks of boron and hydrogen atoms that bridge pairs of boron atoms with H/B ratio of 1.0. This hexagonal borophane exhibits metallic conduction with a conductivity of 0.13 S cm−1 at around room temperature, and a unique metal-to-insulator transition at around 30 °C.
