The Response Wavelength Modulation of Terahertz Detector based on Metal Gratings/Si Blocked-impurity-band Hybrid Structure
Terahertz band detection technology is widely researched, for it brings chemical composition and material quality information of the object. In this work, the metal gratings/Si Blocked-impurity-band (BIB) hybrid structure is proposed. Then, we fabricate two devices with different metallic gratings and one without metallic gratings. The three different devices can response to different wavebands. According to the Fourier spectrum result, the peak wavelengths of the three devices are 15.86, 18.92 and 26 μm, respectively. Our work successfully realizes the modulation of photoelectric response wavelength and provides a novel THz detector for the application of national security, astronomical observation and life sciences.
