Hole Mobility

I think of hole mobility as the ability of “holes” (the absence of electrons) to travel through a metal or semiconductor when an electric field is applied. On the other hand, electron mobility refers to how easily electrons move across a metal or semiconductor under the same conditions.

We often compare these two because they both impact how efficiently a material can conduct electricity. For example, in semiconductors, both hole and electron mobility are important for determining the overall performance of electronic devices.

You might notice that higher mobility in either holes or electrons means better conductivity in materials, which is important for designing effective electronic components

Hole Mobility Formula is defined as follows,
