Abstract

Emerging van der Waals heterojunctions (vdWH) containing 2D materials have shown exciting functionalities that surpass those of traditional devices based on bulk materials. In this Communication, a report on the properties of a 2D sulfide/oxide hybrid vdWH based on n-type molybdenum disulfide (MoS₂) and p-type tin monoxide (SnO) is presented, with promising rectification, thermal-sensing, and photosensing performance. Specifically, the hybrid SnO/MoS₂ vdWH shows static rectification ratio of 2 × 10² with ideality factor of 2.3, and can operate at 100 Hz with good stability. The vdWH shows good temperature stability with reversible and reproducible current levels up to 110 °C, indicating its potential for thermal sensing applications. The sensitivity of current variation is calculated to be 0.0144 dec °C⁻¹. Finally, maximum responsivity of 8.17 mA W⁻¹ and external quantum efficiency of 2.14% have been achieved in photovoltaic measurements. The results suggest that MoS₂–SnO hybrid vdWH are promising for various sensing applications.
