Integrated bidirectional and polarization-sensitive photodetection in a ReSe 2 /graphene/WSe 2 heterostructure

Key Points

• The aim is to develop a photodetector that exhibits both bidirectional and polarization-sensitive properties.
• Developed a ReSe2/graphene/WSe2 heterostructure photodetector
• Evaluated sensitivity to polarization across different wavelengths
• Measured polarization ratio at specified wavelengths
• Achieved a polarization ratio of 9 at 635 nm
• Achieved a polarization ratio of 6 at 808 nm
