Kikuchi lines, known since 1928 [S. Kikuchi, Jpn. J. Phys. 5, 83 (1928)], are generated by irradiating a crystal with high-energy e-beam in SEM or TEM and observing backscattered electrons diffraction on crystalline planes. The Kikuchi line effect gave rise to several useful tools in electron microscopy of crystalline and nanocrystalline materials [K. Saruwatari, et al., J. Mineral. Petrol. Sci. 103, 16 (2007)]. We have discovered a similar diffraction effect but of the crystal’ own thermally emitted electrons.

一种类似于菊池线的新型热电子晶体电子发射效应

Kikuchi 线，自 1928 年以来为人所知 [S. 菊池，日本。J.物理学。5 , 83 (1928)], 是通过在 SEM 或 TEM 中用高能电子束照射晶体并观察晶面上的背散射电子衍射而产生的。Kikuchi 线效应在晶体和纳米晶体材料的电子显微术中产生了几种有用的工具 [K. Saruwatari等人。, J. 矿物。汽油。科学。103 , 16 (2007)]。我们发现了类似的衍射效应，但晶体自身的热发射电子。
