在掃描電鏡下襯度較低的二維材料，如何準(zhǔn)確表征？

其他二維材料

滿足結(jié)構(gòu)有序、在二維平面生長(zhǎng)、在第三維度超薄這三個(gè)條件都算是二維材料，現(xiàn)在除了石墨烯和MoS₂等熱度較高的二維材料之外，很多其他類型的二維材料也相繼被開(kāi)發(fā)出來(lái)。比如和C元素相鄰的B、Si、P、Ge、Sn等元素的單原子層材料，即X烯，如硅烯、磷烯、硼烯；還有二維有機(jī)材料，如二維MOF或COF；還有超薄氮化物，如BN等。

這些二維材料都有著很強(qiáng)的拉曼特征譜峰，所以利用電鏡-拉曼一體化系統(tǒng)對(duì)二維材料的分析表征將會(huì)成為不可或缺的重要手段。
