摘要：

Polarization-sensitive infrared photodetectors are widely needed to distinguish an object from its surrounding environment. Polarization-sensitive detection can be realized by using semiconductors with anisotropic geometry or anisotropic crystal arrangement, such as semiconductor nanowires and two-dimensional (2D) materials. However, these photodetectors show drawbacks in low light absorption, weak polarization sensitivity and stability issues. Here, we designed 2D InAs nanosheet based arrays that are highly suitable for polarization-sensitive infrared photodetection. By using the finite eleme...
