There are several variables like: concentration of electron deficiencies/holes or electrons (n,p) in p/n-type of semiconductor, concentration of donor or acceptor atoms (Nd,Na) in doped semiconductors, length of pn-juction of diode, electron or hole mobility constant (Dn,Dp), etc.
But all of these variables are unreachable for me. At the beginning I thought at least datasheets should include such data but they don't. Just the ones used practically.
Where/How can I access this kind of information?
- BTW: All these variables matter for calculating electron/hole average speed (v), current flux(Φ), density of current (J), which are more theoretical calculations. There are also more practical ones like junction capacitance (matters when reverse-biased) and diffusion capacitance (matters when forward-biased).
