  • 专业解析

    透射电子显微镜(Transmission Electron Microscope,TEM)是一种利用高能电子束穿透超薄样品,通过电子与物质相互作用产生的信号进行微观结构分析的高分辨率成像设备。其核心原理基于电子波的穿透性和电磁透镜的聚焦能力,能够实现原子尺度的观测。

    工作原理

    1. 电子源:采用钨灯丝或场发射枪产生高能电子束,加速电压通常为60-300 kV。
    2. 样品制备:需将样品减薄至100纳米以下,常用方法包括离子减薄和超薄切片技术。
    3. 成像机制:电子穿透样品时发生散射,通过物镜、中间镜和投影镜系统放大成像,最终在荧光屏或CCD相机上形成明暗对比图像。相位衬度和衍射衬度是主要成像模式。
