摘要:

层状二维(2D)材料显示出巨大的应用潜力,特别是在电子领域。我们报道了大规模合成二硒化铂(PtSe 2)的薄膜,这是一种迄今为止几乎没有研究过的过渡金属二硫属化物。重要的是,通过热辅助转化的合成是在400 °C下进行的,代表了这种新型材料与硅(Si)技术直接集成的突破。除了对这种新的2D材料进行全面表征外,我们还展示了其在高性能气体传感应用中的前景,由于薄膜的2D性质,观察到的响应和恢复时间极短。此外,我们实现了垂直堆叠的异质结构的PtSe2在Si上,作为光电二极管和光电池。因此,这项研究建立PtSe2作为下一代传感器和(光)电子器件的潜在候选人,使用与现有Si技术兼容的制造协议。

英文摘要:

Layered two-dimensional (2D) materials display great potential for a range of applications, particularly in electronics. We report the large-scale synthesis of thin films of platinum diselenide (PtSe2), a thus far scarcely investigated transition metal dichalcogenide. Importantly, the synthesis by thermal assisted conversion is performed at 400 °C, representing a breakthrough for the direct integration of this novel material with silicon (Si) technology. Besides the thorough characterization of this new 2D material, we demonstrate its promise for applications in high-performance gas sensing with extremely short response and recovery times observed due to the 2D nature of the films. Furthermore, we realized vertically-stacked heterostructures of PtSe2 on Si which act as both photodiodes and photovoltaic cells. Thus this study establishes PtSe2 as a potential candidate for next-generation sensors and (opto-)electronic devices, using fabrication protocols compatible with established Si technologies.
