“…Due to its high volatility at low temperatures, the fabrication of PbO thin films is frequently challenging. PbO is known to have both a high-temperature orthorhombic phase (β-PbO) and a low-temperature tetragonal phase (α-PbO). , It is possible to fabricate PbO thin films by using several methods, including spray pyrolysis, DC magnetron sputtering, SILAR, metal–organic chemical vapor deposition, and electrodeposition. PbO is an impressive material due to its low electrical conductivity, superior semiconductor, and photoconductive capabilities, suitability for applications involving laser technology, imaging devices, etc. , Moreover, lead and lead oxide structures attract attention with their potential uses in nanodevices and functional materials owing to their regular electronic structure and high optical, sensor, and magnetic characteristics.…”

This study examines the high-frequency-dependent characteristics of the PbO/SnO 2 double-layer semiconductor (DLS) structures. Recently, researchers have been particularly interested in such structures in terms of their use in electrical and photovoltaic applications. A PbO/SnO 2 double layer was successfully coated on a p-type Si substrate (100) wafer with a resistance of 10 Ω cm and a thickness of 280 μm. The Al Schottky (round dot) connections, which have a thickness of 124 nm and a diameter of 1.3 mm, were produced by thermal evaporation. The present study proposes to measure the conductance−voltage (G−V) and capacitance−voltage (C−V) values of the studied Al/PbO/SnO 2 /p-Si Schottky diode for the frequencies of 500 kHz, 800 kHz, and 1 MHz at a temperature of 300 K, which has been suggested for the first time in literature. Due to the presence of surface states (N ss ), PbO/SnO 2 double-layer, and series resistance R s , the C−V and G−V plots show inversion, depletion, and accumulation zones depending on the strong frequency for each frequency tested. Based on the tested frequencies, the reverse-biased C 2 −V curves are used to compute the fundamental electrical characteristics of the Al/PbO/SnO 2 /p-Si structures, including the depletion layer (W D ), Fermi energy level (E F ), diffusion potential (V D ), and thickness barrier height (⌀ B ). We also investigated the capacitance features and the energy density distribution of surface states (N ss ) in the PbO/SnO 2 double-layer structure by utilizing the measured values of G−V and C−V. The values of ⌀ B , V D , and N ss were observed to be 0.54 0.34, and 3.19 10 12 eV −1 cm −2 at 500 kHz, while they were 0.88 0.68, and 1.96 eV −1 cm −2 at 800 kHz and 0.95, 0.75, and 1.47 eV −1 cm −2 at 1 MHz, respectively. It was discovered that the capacitance characteristics of the PbO/SnO 2 double-layer structure were substantially dependent on the applied high frequencies. Furthermore, the C−V and G−V measurements revealed that the series resistance and the interface state density of the studied Al/PbO/SnO 2 /p-Si Schottky diode were critical parameters that significantly affect the electrical parameters offered by the PbO/SnO 2 double-layer nanostructure. The results of the study reveal that the manufactured device exhibits outstanding electric characteristics and support the possibility of using DL thin films in electronic devices.

The present work reports for the first time the design of an electrochemical sensor functionalized with green nanoparticles based on Hyphaene thebaica for amoxicillin quantification. Based on a simple one‐pot bio‐reduction reaction, lead oxide PbO coated with Hyphaene thebaica was synthesized. Ultraviolet‐visible spectroscopy (UV), fourier transform infrared (FITR), transmission electron microscopy (TEM) and X‐ray diffraction (XRD) were used to control optical, structural, morphological, and physicochemical properties of the elaborated nanoparticles. Results demonstrated a good dispersion with a spherical morphology, which is in the order 8 nm. Regarding the good properties of nanoparticles, they are integrated to design an electrochemical sensor for amoxicillin detection. Cyclic voltammetry and square wave voltammetry were used to follow up the sensor modification and the electrochemical sensor response versus different amoxicillin concentrations. Under optimal conditions, the electrochemical sensor modified with the nanoparticles in question provides a linear detection in the range 50–10000 nM, with a detection limit of 0.105 nM. The proposed sensor also exhibits good sensitivity and selectivity against several antibiotic analogues and has been successfully applied to real samples. Aside from its power in several fields including antibacterial, antifungal, enzyme‐inhibiting and antioxidant, green nanoparticles based on Hyphaene thebaica have demonstrated an effectiveness as a sensor for the electrochemical detection of amoxicillin, highlighting the possibility of adopting these sensors as routine test for the environment monitoring.
