Public Abstract	Bismuthene is a 2D material similar to graphene that is usually fabricated on a substrate, which limits its application in electronics and quantum computing. This technology is a method of preparing uniform and substrate-free bismuthene. Each bismuthene nanoflake has an equilateral triangle shape with a 10-100 µm side length and an atomic-thin thickness of 3-10 nm. The nanoflakes are highly crystalline, consisting of bismuth atoms arranged in a honeycomb lattice. Applications for bismuthene include in quantum electronic devices for quantum systems. Advantages: -Substrate-free -Uniform shape -Atomic-thin thickness Potential Applications: -Quantum computing -Spintronic devices -Electronics
