Black-arsenic-based visible–near-infrared photodetector - EurekAlert


<p>Black phosphorus, an emerging two-dimensional material, has recently been incorporated into the family of van der Waals layered materials due to its exceptional electronic and optical properties, such as a tunable bandgap and high carrier mobility, demonstrating substantial potential in the fields of electronics and photonics. The current study successfully developed a dual-band black phosphorus photodetector and validated the feasibility of the device principle. Through comprehensive electrical and photoelectric characterization, the operational mechanism of this device in dual-band light response was elucidated, achieving a peak photoresponsivity of 0.4 A/W and a detectivity of 1.37&times;10<sup>8</sup>&nbsp;Jones. This research underscores the promise of black phosphorus as a versatile material for broadband photodetection, suitable for future optoelectronic applications such as near-infrared sensing and imaging, representing a significant advancement in photodetection technology.</p>
