Polarization-sensitive photodetectors (PSPDs) have
significant applications in both military and civil areas. However,
the current commercial PSPDs require the aid of optical devices
such as polarizers and phase retarders to pick up the polarization
information of light. It is still an arduous task for realizing
filter-free PSPDs. Scientists from China and South Korea prepare
the stable layered β-InSe and achieve high performance filter-free
PSPDs with high photocurrent anisotropic ratio of
0.70.

    The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
