This article reports the fabrication and characterization of nano-structured ITO/ZnO ultraviolet photodetector. A ZnO thin film was deposited by spray pyrolysis technique followed by interdigitated ITO as electrode deposition by RF sputter. Grazing angle x-ray diffraction (GIXRD) study indicates preferential growth along c-axis (002) of thin-film leading nanoneedle formation which was further confirmed by scanning electron microscopy (SEM) imaging. X-ray photoelectron spectroscopy (XPS) analysis of Oxygen 1s (O 1s) was carried out. A peak was observed at 531.8 eV indicating the presence of oxygen vacancy, 530 eV peak relates to the ZnO phase. The bandgap was determined by the Tauc plot; which was found to be 3.22eV. The donor carrier concentration is found to be 8.85x10 18 cm -3 based on room temperature Hall measurement. A near ohmic behaviour was observed which can be interpreted by the existence of high carrier concentration in ZnO. This results in a very thin depletion width of the order of 5nm; therefore, charge transport through the junction is dominated by tunnelling of electrons through depletion width.
本文报道了纳米结构ITO/ZnO紫外探测器的制备与表征。采用喷雾热解法制备ZnO薄膜,然后采用射频溅射法制备交错状ITO电极。掠射角x射线衍射(GIXRD)研究表明,薄膜沿c轴(002)优先生长,导致纳米针形成,扫描电子显微镜(SEM)成像进一步证实了这一点。对氧1s (O 1s)进行了x射线光电子能谱(XPS)分析。在531.8 eV处有一个峰表示氧空位的存在,530 eV处有一个峰与ZnO相有关。带隙由Tauc图确定;结果为3.22eV。根据室温霍尔测量,供体载流子浓度为8.85x10 18 cm -3。观察到近欧姆行为,这可以解释为ZnO中存在高载流子浓度。这导致损耗宽度非常薄,约为5nm;因此,通过结的电荷输运主要是通过耗尽宽度的电子隧穿。

Performance of bi-directional optical network has evaluated for 400 optical network units (ONUs) using RAMAN-EDFA hybrid optical amplifier (HOA). Further, performances have also recorded in terms of quality factor and eye height for the data rate of 5 Gbps, 10 Gbps, 15 Gbps, 20 Gbps and 25 Gbps respectively for the distance of 60 km to 75 km. Limits of the users have also set to 400 for the analysis of various aspects for multiplay services (data, voice, video and mobile service). Data rate of 5 Gbps has delivered the acceptable outcome for multiplay services (MPS). Furthermore, proposed super dense passive optical network (SD-PON) has also shown the stability among the present current research of art in terms of acceptable rating outcome.
