This diagram shows one of the core-shell nanoparticles embedded in a host material, as described in a paper in <i>Advanced Materials</i>. The motion of electrons, as shown by brown lines, is bent in such a way that they appear to be unaffected by the presence of the particle, thus allowing them to pass with little resistance.

In this micrograph of an experimental transistor, blue highlighting indicates areas of "strain," where germanium atoms have been forced closer together than they find comfortable. One of the reasons for the transistor's record-setting performance is that the strain has been relaxed in the lateral direction.
