摘要:

我们报告的集成单层二硫化钼与氮化硅微谐振器组装的粘弹性层转移技术。从谐振器模式到单层的倏逝波耦合通过腔传输的测量来确认。该几何形状的单层半导体薄片的吸收被确定为850 dB/cm,这大于具有相同厚度的石墨烯和黑磷的吸收。该技术可应用于各种单层半导体,用于组装混合光电子器件,例如在宽光谱范围内工作的光电探测器和调制器。

英文摘要:

We report on the integration of monolayer molybdenum disulphide with silicon nitride microresonators assembled by visco-elastic layer transfer techniques. Evanescent coupling from the resonator mode to the monolayer is confirmed through measurements of cavity transmission. The absorption of the monolayer semiconductor flakes in this geometry is determined to be 850 dB/cm, which is larger than that of graphene and black phosphorus with the same thickness. This technique can be applied to diverse monolayer semiconductors for assembling hybrid optoelectronic devices such as photodetectors and modulators operating over a wide spectral range.
