摘要

我们设计并模拟了一种长波红外探测器，该探测器由在薄ii型超晶格(T2SL)下的掺杂半导体地平面组成，并带有金属天线。我们证明了在吸收器带边缘的增强吸收，通过Au图案的几何形状进行光谱调谐。

Engineering the Spectral Response of Long-Wave Infrared Detectors

We present the design and simulation of long-wave infrared detectors consisting of a doped-semiconductor ground plane underneath a thin Type-II superlattice (T2SL), patterned with a metallic antenna. We demonstrate enhanced absorption at the absorber band-edge, spectrally tuned by the geometry of the Au pattern.
