PtTe2 interface engineering for enhanced near‐infrared photoresponse in black silicon photodetectors

InfoMat, EarlyView.
Highly responsive near‐infrared (NIR) photodetectors are essential for advanced photoelectric systems. In this work, a high‐responsivity NIR photodetector is developed by integrating a PtTe2/black silicon (B‐Si) heterostructure into a Si p‐i‐n diode, where B‐Si introduces sub‐bandgap defect states to enhance NIR absorption and the PtTe2 layer induces ...
