Infrared detection devices with self-powered and high polarization sensitivity are motivated by not only the interest in basic science but also the practical applications. Here, we have systematically studied the photoelectronic properties of a chiral (7, 0) single-walled carbon nanotube (SWCNT) with the bending angle θ ranging from 0° to 45° by first-principles. Our results indicate that bending stress can break the spatial inversion symmetry of the SWCNT, which will result in a photocurrent under polarized light. And the maximal photocurre...
