Two-dimensional van der Waals heterojunctions represent a promising avenue for spectrum of optoelectronic endeavors. Nonetheless, their deployment has been somewhat constrained by the suboptimal efficiency photocurrent generated. In this article, ZnO/HfSn2N4 heterojunction is proposed to achieve high photoresponse efficiency. First-principles calculations are utilized confirm that possesses thermal stability with direct bandgap (1.36 eV). It exhibits light absorption coefficient and carrier mobility (2.51 × 103 cm2 V-1 s-1), biaxial strain significant effect on modulation band structure. As tensile increases, changes nonlinearly, transitioning from type-II type-I heterojunction. When compressive decreases. Quantum transport simulations employed calculate density states transmission model, verifying its excellent (a peak reaching 4.93 a02/photon an extinction ratio 75.1). shows potentially efficient photodetector.
