Photocurrent Polarity Switching and Enhanced Photoresponse in Silver Nanoparticles Decorated a-GaN-Based Photodetector

“…A set of lattice planes (111), ( 200), (220), and (311) has been observed at 2θ values 38.17°, 44.30°, 64.48°, and 77.34°, respectively, which correspond to crystallographic planes of face centered cubic (FCC) structure of Ag NPs. 20 The high-resolution TEM image 200), (220), and (311) planes of metallic silver can be seen, confirming the highly crystalline nature of Ag NPs. These planes correspond to the typical lattice spacing of 0.236, 0.205, 0.145, and 0.122 nm, respectively.…”

“…The sharp and distinct peaks in the graph correspond to the planes from which the diffraction occurred. A set of lattice planes (111), (200), (220), and (311) has been observed at 2θ values 38.17°, 44.30°, 64.48°, and 77.34°, respectively, which correspond to crystallographic planes of face centered cubic (FCC) structure of Ag NPs . The high-resolution TEM image shown in Figure (b) depicts the Ag NPs possessing similar sized spherical, pseudospherical, rectangular, and some triangular morphologies.…”

Sulfated lignocellulose nanofibril supported flower-like BiOBr with oxygen vacancies towards absorption–photocatalytic synergetic removal of organic pollutants

“…With the vigorous development of papermaking, printing and pharmaceutical industries, a large number of organic pollutants have been discharged into water bodies, and caused serious pollution; it poses a huge threat to the global ecosystem and human health. [1][2][3][4][5][6] Semiconductor photocatalytic technology is considered as a promising strategy for the removal of organic pollutants from wastewater because of its strong oxidation ability, excellent photochemical stability and sustainability. [7][8][9] Among all semiconductors, bismuth oxyhalide (BiOX, X = Cl, Br, I) semiconductors have good industrial application prospects (e.g., photocatalysis, pharmaceuticals, gas sensors, and optoelectronics).…”

Enhancing mid-infrared surface phonon polariton modes: optimization of structural parameters in Nb-doped SrTiO3 with hole array structures for advanced infrared sensors

“…Niobium (Nb)-doped STO materials, which exhibit electrical conductivity [22] and a negative real permittivity within the 8-14 µm atmospheric window band [23], have been extensively utilized in civilian sectors, including infrared thermography [24], medical applications [25], and remote sensing [26]. This distinctive property renders them highly advantageous for phonon enhancement applications in the development of infrared detectors.…”
