Two-dimensional (2D) semiconductors have attracted vital scientific curiosity due to their optical properties. Their functions in optoelectronic gadgets could be additional expanded by combining them to kind heterostructures. We characterised a WTe2–2D Te heterostructure by native probing of the photocurrent with respect to the magnitude, section, and place. Photocurrent era throughout the machine is split into distinct areas: photo-thermoelectric results happen solely on the 2D Te–Au junction space, PV-dominant results on the 2D–WTe2 interface, and thermoelectric-to-photovoltaic crossover results on the WTe2–2D Te overlap space. These completely different photocurrents can’t be fused right into a single area as a result of every space is ruled by completely different era mechanisms, which depend upon the situation of the machine. The ability dependence of every photocurrent sort additionally varies throughout the machine. Our outcomes point out that cautious materials choice and machine construction design, based mostly on the digital, optical, and thermal properties of the channel supplies, are important to keep away from forming completely different optoelectronic puddles that might counteract one another inside a single machine.
