本发明属于光热转换与电磁波调控技术领域,公开了一种增强太赫兹光热效应的完美吸收结构及制备方法。该结构由吸收层二维MXene纳米薄膜吸收层、Fabry–Pérot谐振腔层和金反射层依次构成,MXene薄膜与金反射层之间形成Fabry–Pérot谐振腔。本发明通过调控MXene等效电磁阻抗和Fabry–Pérot谐振腔的腔长,使入射太赫兹波的表面直接反射波与腔内多次反射波发生相位相消,显著抑制系统反射;同时金反射层完全阻断透射,使入射电磁能量几乎全部耗散于吸收层,实现全吸收。本发明可最大限度将入射能量转化为热能,显著增强纳米MXene薄膜的光热效应与转换效率,适用于光热探测、太赫兹功率计等领域。
