  • 專業解析

    透射電子顯微鏡(Transmission Electron Microscope,TEM)是一種利用高能電子束穿透超薄樣品,通過電子與物質相互作用産生的信號進行微觀結構分析的高分辨率成像設備。其核心原理基于電子波的穿透性和電磁透鏡的聚焦能力,能夠實現原子尺度的觀測。

    工作原理

    1. 電子源:采用鎢燈絲或場發射槍産生高能電子束,加速電壓通常為60-300 kV。
    2. 樣品制備:需将樣品減薄至100納米以下,常用方法包括離子減薄和超薄切片技術。
    3. 成像機制:電子穿透樣品時發生散射,通過物鏡、中間鏡和投影鏡系統放大成像,最終在熒光屏或CCD相機上形成明暗對比圖像。相位襯度和衍射襯度是主要成像模式。
