Abstract :
In this letter, we report an analog small signal amplifier based on semiconducting black phosphorus (BP), the most recent addition to the family of 2D crystals. The amplifier, consisting of a BP load resistor and a BP field-effect transistor (FET), was integrated on a single flake. The gain of the amplifier was found to be ~9 and it remained undistorted for input signal frequencies up to 15 kHz. In addition, we also report record high ON current of 200 μA/μm at VDD = -0.5 V in the BP FETs. Our results demonstrate the possibility for the implementation of BP in the future generations of analog devices.
