“…This indicates that the UV light sensor has not only a high response, but also a good reversibility. Compared with other reported UV sensors based on different metal oxide materials in the literature, such as WO3 [29], SnO2 [30], TiO2 [31] and ZnO [32,33], the UV sensors based on porous In2O3 nanoparticles in this study have better sensing performance (i.e., the response) than most UV sensors at room temperature.…”

2019) Ultra-sensitive UV and H2S dual functional sensors based on porous In2O3 nanoparticles operated at room temperature. Journal of Alloys and Compounds, 770. pp. 721-731. AbstractA dual functional sensor for detecting both UV light and H2S gas was fabricated using the hexagonal phase porous In2O3 nanoparticles, which were prepared using the hydrothermal and calcination process. The porous In2O3 nanoparticles with large surface areas and pore volumes could provide plenty of active sites to produce much active oxygen species, which were beneficial for the UV light and H2S gas sensing reactions, thus resulting in a good sensing performance. At room temperature, the dual functional sensor based on porous In2O3 nanoparticles exhibited ultra-high responses for sensing both UV light (with a wavelength of 365 nm) and H2S gas. As a UV sensor, its response was 12886.0 for a UV power intensity of 1.287 mW/cm 2 and its detection limit was 0.013 mW/cm 2 . As a H2S gas sensor, the sensor exhibited an ultra-high response (26268.5 to 1 ppm H2S) and a very low detection limit (1ppb of H2S), and it also have excellent selectivity, reversibility and stability. 2

“…Regarding the means of energy utilization, multiple functions could be combined into a single chip for high-level integration. As introduced earlier, both gas sensing and photodetection functions were realized on a multifunctional hybrid device by integrating multiple units [78], [81]. Nevertheless, M. Reddeppa et al [95] fabricated a solution-processed Au@rGO/GaN nanorods (NRs) hybrid This work has been submitted to the IEEE for possible publication.…”

“…As an emerging concept, the PV self-powered gas sensing has been achieved by using different strategies. In view of different sensing principles, we mainly identify four types of PV self-powered sensing strategies including integrated gas sensor and solar cell [76]- [78], integrated light filter and solar cell [79]- [83], gas-sensitive heterojunction photovoltaics [84]- [97], and gas-sensitive lateral photovoltaics [98]- [101]. as sketched in Fig.…”

We develop a covariant kinetic theory for massive fermions in curved spacetime and external electromagnetic field based on quantum field theory. We derive four coupled semi-classical kinetic equations accurate at O( ), which describe the transports of particle number and spin degrees of freedom. The relation with the chiral kinetic theory is discussed. As an application, we study the spin polarization in the presence of finite Riemann curvature and electromagnetic field in both local and global equilibrium states.

“…A novel self‐powered photodetector that works without an external power source, which can meet the demands of a small size, reduced weight, and low power consumption for next‐generation nanodevices, is being widely studied. One kind of self‐driven photodetector has been designed by utilizing the photovoltaic effect . According to the charge separation features of the interface, the current self‐driven photosensors based on the photovoltaic effect can be classified into three types: Schottky junction, p–n junction, and photoelectrochemical (PEC) cell.…”

Novel self‐powered nanoscale photodetectors that can work without an external power source, which have great application potential in next‐generation nanodevices that operate wirelessly and independently, are being widely studied. This review aims to give a comprehensive summary of the state‐of‐the‐art research results on self‐powered nanoscale photodetectors. An introduction of recent progress on Schottky junction photodetectors is provided. Two types of Schottky junctions are discussed in detail: metal–semiconductor and semiconductor–graphene junctions. Next, recent developments of p–n junction photodetectors are highlighted, including homojunction and heterojunction photodetectors. Then, piezo‐phototronic effect enhanced photodetection performances of Schottky junctions and p–n junctions are discussed. Then, significant results on the photoelectrochemical‐cell‐based photodetector and integrated self‐powered nanosystem are presented, followed by a systematic comparison of different types of photodetectors. Finally, a summary of the previous results is given, and the major challenges that need to be addressed in the future are outlined. The hope is that this review can provide valuable insights into the current status of self‐powered photodetectors and spur new structure and device designs to further enhance photodetection performance.
