“…Nevertheless, as compared to isolated systems, the heterostructure indicated an improved absorption throughout the visible region. This enhancement enables photodetectors [15], photocatalytic applications [38] etc. The trend of enhancement of absorption coefficient is consistent with the results obtained for other TMDC/ wide band gap semiconductor based heterostructures [16-18, 39, 40].…”

We report a study on the stability, optical absorption, and modulated electronic properties of the ZnO(000-1) and MoS2 Van der Waals (VdW) heterostructure using density functional theory. We employed a supercell of ZnO/MoS2 hybrid and specifically explored the effects of creating an interface with the O-terminated face of ZnO while considering the interlayer interaction. We observed an increase in the band gap opening of MoS2 within the hybrid structure (1.37 eV) is primarily attributed to in-plane strain, with minimal contribution from the identified charge transfer occurring from MoS2 to ZnO. Notably, the hybrid structure exhibits enhanced photo absorption in the visible and near-infrared regions, highlighting their significance for optoelectronic applications.

“…To resolve the global energy crises and pharmaceutical issues, development of an efficient electrode materials having bifunctional capabilities especially for the detection of L-Cysteine as well as supercapacitor applications, is urgently required. In this perspective, until now various metal oxides based bi-functional materials are being employed for energy as well as sensing applications [6][7][8][9][10][11]. However, these electrode materials are facing serious problems of low energy and cyclic instability in supercapacitors and poor sensitivity for sensor which hinder their practical utilization.…”

Bi-functional materials provide an opportunity for the development of high-performance devices. Up till now, bi-functional performance of NiCo2O4@SnS2 nanosheets is rarely investigated. In this work, NiCo2O4@SnS2 nanosheets were synthesized on carbon cloth by utilizing a simple hydrothermal technique. The developed electrode (NiCo2O4@SnS2/CC) was investigated for the detection of L-Cysteine and supercapacitors applications. As a non-enzymatic sensor, the electrode proved to be highly sensitive for the detection of L-cysteine. The electrode exhibits a reproducible sensitivity of 4645.82 µA mM-1 cm-2 in a wide linear range from 0.5 to 5 mM with a low limit of detection (0.005 μM). Moreover, the electrode shows an excellent selectivity and long-time stability. The high specific surface area, enhanced kinetics, good synergy and distinct architecture of NiCo2O4@SnS2 nanosheets produce a large number of active sites with substantial energy storage potential. As a supercapacitor, the electrode exhibits improve capacitance of 655.7 Fg-1 at a current density of 2 A g−1 as compare to NiCo2O4/CC (560 Fg-1). Moreover, the electrode achieves 95.3 % of its preliminary capacitance after 10,000 cycles at 2Ag−1. Our results show that NiCo2O4@SnS2/CC nanosheets possess binary features could be attractive electrode material for the development of non-enzymatic biosensors as well as supercapacitors.
