“…A high absorption efficiency (~100%) along with a 'R' value of~2 mA W −1 has been demonstrated through simulation analysis. Vahdani et al [15] recently reported a platinum silicide (PtSi)-Si junction Schottky barrier PD with 84% incident light absorption (at wavelength of 4.3 µm) for sensing of CO 2 gas. However, the responsivity has not been addressed.…”

Plasmonically enhanced light absorption in Schottky barrier photodetectors (PDs) can be achieved by engineering metallic nanostructures. In this context, gold (Au) gratings on titanium (Ti)/silicon carbide (SiC) based Schottky barrier is proposed in this work for photodetection application. Further, the effects of various grating parameters and incident angle on absorbance are demonstrated. The grating based structure is able to provide ~85% incident light absorption leading to a significantly high responsivity value as compared with that of conventional (without metallic grating) structure. High unbiased responsivity values of 4.396 mA W−1 and 2.496 mA W−1 are obtained for Au/Ti/6H-SiC Schottky barrier PD at wavelengths of 694.5 nm and 1035 nm, respectively based on Fowler’s model. In view of advanced properties of SiC, the present work will open new opportunities for plasmonic PDs based on SiC platform.
