Abstract Two‐dimensional (2D) heterostructures have sparked widespread interest in physics and device applications. The interfacial band alignment engineering of 2D opens promising routes for high‐performance electronics optoelectronics. In this study, a Te/MoS 2 interface is engineered by tailoring the lattice mismatch distance, which changed alignment. photocurrent significantly increased optimizing corresponding designed to function as an ultrasensitive photodetector with light on/off ratio 10 4 , responsivity ≈1047 A W −1 detectivity >5 × 12 Jones, well spectral detection capability up 1550 nm. proposed methods are robust versatile can be used produce desired electronics; hence, study may broaden scope heterostructure
