Query: Polarization-sensitive and broadband photodetection based on a
  mixed-dimensionality TiS3/Si p-n junction   The capability to detect the polarization state of light is crucial in many
day-life applications and scientific disciplines. Novel anisotropic
two-dimensional materials such as TiS3 combine polarization sensitivity, given
by the in-plane optical anisotropy, with excellent electrical properties. Here
we demonstrate the fabrication of a monolithic polarization sensitive broadband
photodetector based on a mixed-dimensionality TiS3/Si p-n junction. The
fabricated devices show broadband responsivity up to 1050 nm, a strong
sensitivity to linearly polarized illumination with difference between the two
orthogonal polarization states up to 350 % and a good detectivity and fast
response time. The discussed devices can be used as building blocks to
fabricate more complex polarization sensitive systems such as polarimeters.
