Time-current characteristics of ZrO2/Si photodetector

The text files contain data regarding the time-current characteristics of photodetectors comprised of a zirconium oxide (ZrO2) layer on top of a p-type silicon (Si) substrate. The thickness of the layer is approximately 5 nm. The bottom electrode of the device was made of aluminum, while the top contact consisted of tin indium oxide (ITO). During the measurement, the samples were illuminated with light pulses of the frequency specified in the filename. The light source used, whether a laser with a wavelength of 1064 nm or an LED with a wavelength of 940 nm, was also indicated in the filename. Additionally, if the sample was poled before the measurement, it is specified in the filename. One distinctive file, "ZrO2_TV_Remote.dat," contains data collected by the photodetector while illuminated with a conventional TV remote. The light spectra of the TV remote are available in the file named "TV_remote_spectra.dat". The wavelength of the maximum intensity is approximately 932 nm. The power of the light is approximately 2 mW, and the signal frequency is approximately 36 kHz. The remote operates under the standard RC5 protocol. This file provides specific information about the response of the photodetector to the signals emitted by a TV remote.本数据集的文本文件包含基于p型硅（p-type silicon, Si）衬底上沉积氧化锆（zirconium oxide, ZrO₂）薄膜的光电探测器（photodetector）的时间-电流特性数据。该氧化锆薄膜的厚度约为5 nm。该器件的底电极采用铝制备，顶电极则为氧化铟锡（tin indium oxide, ITO）。 测试过程中，样品由文件名中注明频率的光脉冲辐照。所用光源（包括波长1064 nm的激光或波长940 nm的发光二极管（LED））同样会在文件名中标注。此外，若样品在测试前经过极化处理，该信息也会在文件名中注明。 其中一个特殊文件为"ZrO2_TV_Remote.dat"，其数据为光电探测器在传统电视遥控器辐照下的响应数据。该电视遥控器的发光光谱可在名为"TV_remote_spectra.dat"的文件中获取，其发光强度峰值对应的波长约为932 nm，光功率约为2 mW，信号频率约为36 kHz，且采用标准RC5通信协议。该文件详细记录了光电探测器对电视遥控器发射信号的响应特性。
