2024.11.26
The research team fabricated a nMAG/epi-Si detector with low defect density and spectral dependence, which has high responsivity and detectivity at a wavelength of 1550 nanometers, suitable for near-infrared optical communications and high-resolution imaging. It has high gain and self-quenching characteristics under low reverse bias, which reduces noise and improves signal stability. In addition, the low noise and fast response of the detector enable it to achieve a data transmission rate of 38 Mbps. These characteristics indicate that nMAG/epi-Si heterostructures have great potential in the fields of infrared detection and optical communications.
