Summary: Designing heterostructure materials at the nanoscale is a well-known method to enhance gas sensing performance. In this study, ZnO/SnO2 heterostructures were grown on alumina substrates using the ultrasonic spray pyrolysis method. The results showed that the sensitivity of the sensor to H2S gas can be altered by changing the zinc chloride content in the precursor, and the heterostructures with a 5:1 ratio of ZnCl2 to SnCl2·2H(2)O exhibited the highest response. The gas sensing mechanism of the ZnO/SnO2 heterostructures was analyzed and attributed to the formation of the heterostructure between ZnO and SnO2.

Summary: Incorporating high permittivity inorganic ferroelectric materials into polymer dielectrics can significantly improve their energy storage capacity. However, the discrepancy in permittivity and the high remnant electric displacement of ferroelectric materials limit the discharged energy density. In this study, a novel nano-heterostructure filler consisting of antiferroelectric nanoparticles (PLSZST) encapsulated with an Al2O3 layer was proposed to alleviate the permittivity discrepancy and enhance the breakdown strength. Experimental and computational results demonstrated that the presence of the Al2O3 layer effectively enhanced the electric displacement and breakdown strength, while reducing the remnant displacement and inhibiting the formation of electrical trees. The nanocomposite films prepared with this filler exhibited impressive discharged energy density and energy storage efficiency near the high electrical breakdown strength, outperforming the current PVDF-based composite dielectrics for high-power energy storage capacitors.

Summary: This study establishes a theoretical relationship between the properties of a two-dimensional electron gas (2DEG) in AlGaN/GaN HEMT heterostructure and various gas-sensing characteristics. It is proposed that using a thinner barrier layer in the heterostructure can lead to lower detection limits, higher sensing response, and faster response time. Experimental results confirm these analytical findings by comparing a thin-barrier gas sensor with a thick-barrier gas sensor.
