effective mass
« on: March 17, 2015, 12:58 »
can i calculate  effective mass in my device?and how?what is the relationship between effective mass and conductivity?
Thank you !

Please have a look at these two tutorial dealing with effective mass:
Meta-GGA and 2D confined InAs
Effective mass of electrons in silicon

Thank you.and i want to know how to calculate the effective mass in device with different bias,calculating the conductance for different gate potentials.

The effective mass is a bulk property, and not bias-dependent.
