Indicate the direction in which the electrons in the valence and
conduction band will move in the dispersion relation when an
electric field is applied in the [100] direction. The figure below
shows the dispersion relation of silicon in the [111] and [100]
directions. It also shows the location of the thermally excited
electrons (black dots) and holes (circles) at room
temperature.![4 Conduction band Si 3 Valence band 0 [100] P Crystal momentum hk](http://img.homeworklib.com/images/88d4a7f6-7ab9-4ea0-b0f5-71f2873c501d.png?x-oss-process=image/resize,w_560)
