Effective mass of Si in semiconductor physics

Click For Summary
SUMMARY

The effective mass of silicon (Si) in semiconductor physics is crucial for understanding tunneling current in devices such as p-n junction diodes doped with Boron and Phosphorus. The discussion emphasizes the distinction between transport effective mass and density effective mass, advising users to apply the transport effective mass when calculating transport phenomena and the density effective mass for electron density calculations. It is essential to approach the effective mass concept as a simplification that allows the application of Newton's laws in a quantum context.

Hello,

I have the problem, from Sze' book, tunneling current, what is m*?
I want to konw the value of it.
The m* has many reference, how do I select?

My interested device is diode that was doped with Boron and Phosphorus for p-n junction.

Thank very much.

when you calculate the transport, use the transport effetive mass, when you deal with electron density, use the density effetive mass.
dont care about the effictive mass concept, just imagine the electron with this mass could be dealt with using Newton's law, (and of course it should be quantumm's law if using its real mass)
