## How do you find the effective mass of an electron?

## What is the effective mass and energy band minima and Maxima?

**Effective mass and**energy band minima**and**maxima**of**Ge, Si**and**GaAs. The values**of**the energy band minima**and**maxima as well as the**effective**masses for germanium, silicon**and**gallium arsenide are listed in the table below: m0 = 9.11 x 10-31 kg is the free**electron**rest**mass**.

## How do you calculate the effective mass of a semiconductor?

- The
**effective mass of**a semiconductor is obtained by fitting the actual E-kdiagram around the conduction band minimum or the valence band maximum by a parabola. While this concept is simple enough the issue turns out to be substancially more complex due to the multitude**and**the occasional anisotropy**of**the minima**and**maxima.

## What is electronic effective mass and why is it important?

- As it simplifies the more general band theory, the electronic
**effective mass**can be seen as an important basic parameter that influences measurable properties**of**a solid, including everything from the efficiency**of**a solar cell to the speed**of**an integrated circuit.
