摘要

文章展示了基于黄铜矿的 CuGaTe2 直接带隙（1.18 eV）光电探测器（PD）的设计和建模，该光电探测器具有极佳的光学和电子特性，并在光电探测器上表现出卓越的性能。在整个研究过程中，我们通过切换特定层的宽度、载流子密度和缺陷密度，以及特定界面的界面缺陷密度，对该光电探测器进行了研究。为了提高光电探测器的性能，对各层进行了优化。此外，还分析了各种器件电阻的影响。异质结构光电探测器的 JSC 和 VOC 分别为 38.27 mA/cm2 和 0.94 V。波长为 920 nm 时，最大响应率 R 和检测率 D* 分别为 0.663A/W 和 1.367 × 1016 Jones。光谱响应在 800 到 1000 nm 的光波长范围内具有非常高的值，这证实该装置能够检测近红外（NIR）光区。这项工作为制造具有更高性能的 CGT 材料光电探测器提供了重要指导。

Unveiling the potentiality of a self-powered CGT chalcopyrite-based photodetector: theoretical insights

The article demonstrates the design and modelling of CuGaTe₂ direct bandgap (1.18 eV) chalcopyrite-based photodetector (PD), which has superb optical and electronic characteristics and shows remarkable performance on the photodetector. The photodetector has been investigated throughout the work by switching width, carrier and defect densities of particular layers and also the interface defect density of particular interfaces. The various layers have been optimized for the higher performance of the PD. Also, the impression of various device resistances has been analyzed. The J_SC and V_OC of the heterostructure photodetector is found to be 38.27 mA/cm² and 0.94 V, in turn. The maximum responsivity, R and detectivity, D* are found to be 0.663A/W and 1.367 × 10¹⁶ Jones at a wavelength of 920 nm. The spectral response has a very high value in the range of 800 to 1000 nm light wavelength, which confirmed that this device is capable of detecting the near infrared (NIR) region of light. This work gives important guidance for the manufacture of CGT material-based photodetectors with higher performance.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
