Effective photoconductivity of exfoliated black phosphorus for optoelectronic switching under 1.55 μm optical excitation Effective photoconductivity of exfoliated black phosphorus for optoelectronic switching under 1.55 lm optical excitation
International audience
We present a microwave photoconductive switch based on exfoliated black phosphorus and strongly responding to a 1.55 lm optical excitation. According to its number of atomic layers, exfoliated black phosphorus presents unique properties for optoelectronic applications, like a tunable direct bandgap from 0.3 eV to 2 eV, strong mobilities, and strong conductivities. The switch shows a maximum ON/OFF ratio of 17 dB at 1 GHz, and 2.2 dB at 20 GHz under 1.55-lm laser excitation at 50 mW, never achieved with bidimensional materials.
