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.
