Characterization and Humidity Sensing Properties of the Sensor Based on Na2Ti3O7 Nanotubes

Journal of Nanoscience and Nanotechnology (2014)

Yupeng Zhang Jian Wu Ying Zhang Wenbin Guo Shenping Ruan

Na2Ti3O7 nanotubes was synthesized by a hydrothermal method, and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Then the material was coated on Al2O3 ceramic substrate to fabricate humidity sensors using Ag-Pd as interdigitated electrodes. The sensor shows high humidity sensitivity and quick response-recovery time. The impedance changes about five orders of magnitude within humidity range from 11% to 95% relative humidity (RH). At the frequency of 100 Hz, the response time is 2 s and recovery time is 4 s, and the maximum hysteresis is less than 3% RH. Moreover, complex impedance property at different RH was investigated to study sensing mechanism. The results indicate the potential applications of Na2Ti3O7 nanotubes for fabricating high-performance humidity sensors.

Sodium Titanate Nanorod Moisture Sensor and Its Sensing Mechanism

IEEE Electron Device Letters (2013)

Yupeng Zhang Ying Zhang Bo Fu Wei Li Wenbin Guo

Sodium titanate Na ₂ Ti ₆ O ₁₃ nanorods were synthesized by a hydrothermal method and characterized by X-ray diffraction and scanning electron microscopy. Then, the material was coated on a Al ₂ O ₃ ceramic substrate to fabricate humidity sensors using Ag-Pd as interdigitated electrodes. The sensor shows high humidity sensitivity and fast response and recovery. The impedance changes by five orders of magnitude over a relative humidity (RH) range from 11% to 95%. At the frequency of 100 Hz, response and recovery times are both <;2 s, and the maximum hysteresis is <;3% RH. In addition, the complex impedance at different RH was investigated to understand the sensing mechanism. The results indicate potential applications of sodium titanate for fabricating high-performance humidity sensors.

Sol-Gel Synthesized Amorphous (InxGa1−x)2O3 for UV Photodetection with High Responsivity

Sensors (2024)

Yupeng Zhang Ruiheng Zhou Xinyan Liu Zhengyu Bi Shengping Ruan

β-Ga2O3 photodetectors have the advantages of low dark current and strong radiation resistance in UV detection. However, the limited photocurrent has restricted their applications. Herein, MSM UV photodetectors based on (InxGa1−x)2O3 (x = 0, 0.1, 0.2, 0.3) by a sol-gel method were fabricated and studied. The doping of indium ions in Ga2O3 leads to lattice distortion and promotes the formation of oxygen vacancies. The oxygen vacancies in (InxGa1−x)2O3 can be modulated by various proportions of indium, and the increased oxygen vacancies contribute to the enhancement of electron concentration. The results show that the amorphous In0.4Ga1.6O3 photodetector exhibited improved performances, including a high light-to-dark current ratio (2.8 × 103) and high responsivity (739.2 A/W). This work provides a promising semiconductor material In0.4Ga1.6O3 for high-performance MSM UV photodetectors.

An efficient MSM UV photodetector with an ultra-low dark current enhanced by a back to back TiO2/PbTiO3 PN heterojunction

Applied Physics Letters (2023)

Yupeng Zhang Ruiheng Zhou Shengping Ruan Yan Ma Caixia Liu

A TiO2 MSM UV photodetector has been extensively researched and exhibits many good properties such as stability and a large ratio of light to dark current. However, it suffers from a high dark current and slow response and recovery. In this work, an MSM UV photodetector based on a TiO2/PbTiO3 heterojunction was fabricated by a sol-gel method. Spontaneous polarization of ferroelectric perovskite PbTiO3 can deplete carriers and accelerate the separation and transport of photo-generated carriers. The photodetector showed enhanced performances, including an ultra-low dark current (1.146 19 × 10−11 A), an improving ratio of light to dark current, as well as short response and recovery times (decreasing to 65 and 81 ms). These results indicate the potential in the combination of ferroelectric perovskite PbTiO3 with traditional wide bandgap semiconductor materials to fabricate high-performance UV photodetectors.

Application of Solution-Processed V2O5 in Inverted Polymer Solar Cells Based on Fluorine-Doped Tin Oxide Substrate

Journal of Nanoscience and Nanotechnology (2014)

Jian Wu Yupeng Zhang Yeyuan He Chunyu Liu Wenbin Guo

We used a hydrothermal method to synthesis the solution-processed V2O5 as anode buffer layer, which applied on inverted polymer solar cells based on FTO substrate. The structure of the device is glass/FTO/TiO2/P3HT:PCBM/V2O5/Ag. We discussed the dependence of device performance on the concentrations of V2O5 solution. It is found that when the concentration of V2O5 is 300 microg/ml, the power conversion efficiency (PCE of 2.38%) is the highest, which is much higher than that of the device without anode buffer layer (PCE of only 0.87%). Moreover, it can significantly reduce the energy consumption and make it more cost-effective.
