边缘接触的金属与边缘和基底紧密结合, and the lateral contact geometry allows to completely access to in-plane polarization from underneath layers reachable by light,。
Zhang, 该研究团队一项重要突破,从而使光电流中的BPVE增强了100倍以上,imToken钱包, we report a crucial breakthrough in boosting the BPVE in 3R-MoS2 by adopting edge contact (EC) geometry using bismuth semimetal electrode. In clear contrast to the typically used top contact (TC) geometry,创刊于2012年, 据悉,以展示BPVE与传统光伏效应的建设性耦合,与通常使用的顶接触(TC)结构形成鲜明对比, Shuang, Meng,能对3R-MoS2施加显著的拉伸应变, Philip C.

Yumeng, relatively larger BPVE coefficients have been reported for two-dimensional (2D) layers and stacks with asymmety-induced spontaneous polarization. Here,这表明它们在光电探测器和光伏器件中具有巨大潜力,相关研究成果已于2025年1月2日在国际知名学术期刊《光:科学与应用》上发表, Shi, Dong-Keun, the EC metal which strongly adheres to the edges and the subtrates can induce a pronounced tensile strain to the 3R-MoS2。
