Umklapp process [′u̇m‚kläp ‚prä·səs] (solid-state physics) The interaction of three or more waves in a solid, such as lattice waves or electron waves, in which the sum of the wave vectors is not equal to zero but, rather, is equal to a vector in the reciprocal la...

In electronic transport, umklapp processes play a fundamental role as the only intrinsic mechanism that allows electrons to transfer momentum to the crystal lattice and, therefore, provide a finite electrical resistance in pure metals1,2. However, umklap

In similarity with observations on the 21×21 surface prepared by adding Au to the Ag/Si(111) 3×3 surface [21], gaps in the surface band structure open up in regions of the two-dimensional k-space where the umklapp branches of the S1 bands cross each other. The Fermi level is ...
反转散射,物理学术语。内容简介 Umklapp散射(也称U-过程或Umklapp过程)是一种变换,如反射,矢量波,电子晶格势散射或非谐波声子 - 声子(或电子 - 声子)散射过程,反映电子状态或在第一布里渊区外形成具有动量k向量的声子。 Umklapp散射是限制结晶材料中热导率的一个过程,其他过程是晶体缺陷处的声子散射。对于...
