Abstract:

Two-dimensional (2D) materials have become the promising channel materials for optoelectronic applications. In this regards, few layered Black Phosphorus (BP) has shown a significant potential, due to its ultrathin layered structure, high carrier mobility, mechanical flexibility and thickness dependent direct band gap ranging from 0.3 eV (bulk) −2.0 eV (monolayer). Herein, we will be presenting the latest results obtained on the fabricated device based on thin layer BP channel. The fabricated device exhibits p-type transport with high hole mobility at low Vds. The device shows a linear increase in photocurrent as a function of laser power and exposure duration. The results confirm high photoresponsivity from the device under white light illumination. Further, a long photocurrent decay time characteristic confirms the single type of traps dominating the process. The obtained results are significant and can be of interest to the researchers involved in the 2D materials for potential photodetector applications. Recent publications 1.
