However, conventional materials such as InGaAs, and HgCdTe face significant challenges, such as complex fabrication with high costs and limited room-temperature NIR sensitivity. Here, we report the chemical vapor deposition (CVD)-driven epitaxial growth of wafer scale lead sulfide (PbS) single-crystal films on SrTiO<sub>3</sub> (STO) substrates. The single-crystal films exhibit exceptional crystallinity with highly oriented domains alignment. By constructing an asymmetric Au-Cr/PbS/InZnO (IZO) structures, the devices were enabled with efficient photoresponse. The Schottky contact not only induces a substantial photovoltage under infrared light, breaking through the cryogenic operation limitation of traditional Pb-based devices, but also leads to sub-millisecond response (<em>τ</em><sub>rise</sub>/<em>τ</em><sub>fall</sub> = 0.57/0.68 ms). Through the synergistic integration of the high-quality single-crystalline film with the asymmetric interfacial engineering, we achieve room-temperature, zero-bias infrared imaging. As a result, the devices exhibit a specific detectivity <em>D</em>* of 9.8 × 10<sup>10</sup> cm Hz<sup>1/2</sup> W<sup>−1</sup>, offering a scalable pathway toward low-cost, uncooled infrared imaging systems and demonstrating significant potential for practical applications.</div></div>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":"71 7","pages":"Pages 1669-1676"},"PeriodicalIF":21.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147321097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that implementing single mitigation measures may increase food costs and exacerbate inequality without achieving the target carbon emission mitigation goal.

However, low temporal resolution and the lack of accurate in-situ surface observations have limited understanding of the magnitude of these variations. Here, we report analysis results of the in-situ infrared spectra at the same location across different local times acquired by the Chang'e-6 lander. The in-situ spectra were calibrated for thermal contributions based on laboratory measurements conducted on the returned lunar soils, showing clear OH/H<sub>2</sub>O absorption signals. The OH/H<sub>2</sub>O contents achieved from the in-situ spectra exhibit significant temporal variations, with a notable decrease of 37%-58% from ∼10:00 a.m. to ∼11:03 a.m. local time. The discovery confirms not only the diurnal water variations detected by remote sensing but also extends such variations to the hourly range. The OH/H<sub>2</sub>O content decreasing rate is ∼8.4 ± 0.4 ppm/K in the high temperature range (349-358 K), faster than in the low temperature period (∼5.5 ppm/K for 309 K to 319 K). This indicates that temperature exerts a dominant control on the variation of OH/H<sub>2</sub>O content. Hydrogen exists in various forms in lunar soil grains and solar wind flux over a lunar day is insufficient to replenish the depleted OH/H<sub>2</sub>O. Therefore, the occurrence of OH/H<sub>2</sub>O, the only form detectable by infrared spectroscopy, is highly temperature dependent. The new discoveries shed light on the distribution and recycling of water on the lunar surface.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147759033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
