1. Layer-dependent Bandgap: Unlike graphene, black phosphorus has a bandgap that varies from about 0.3 eV in bulk form to 2 eV in monolayer form. This tunable bandgap is crucial for designing semiconductor devices. 2. High Carrier Mobility: Black phosphorus exhibits high carrier mobility, which is essential for high-speed electronics. 3. Anisotropic Properties: Its properties vary significantly along different crystallographic directions, which can be advantageous for designing anisotropic nanodevices. 4. Strong Light Absorption: It absorbs a broad spectrum of light, making it suitable for photodetectors and solar cells.
