Why do holes have effective mass although being vacant energy states ?

Hi Sushin,

In solid state physics, a particle'seffective mass(often denoted $\text{[math]}$ ) is themassthat itseemsto have when responding to forces. Here, although we define and understand holes as vacancies, when they "move" towards the positive terminal under the electrical field, the concept of effective mass is introduced.

Hope this helps.
