For a length within the ballistic regime, why the current value changing with the length ?
Ok, I considered the relaxation time to find the relaxation length ( L = tau * Vf = 36.8 um ; taking Vf = 8.10^5m/s )
And so I chose 2 values for the length which were much less than this value, this should mean ballistic regime right ? (If my logic is flawed, this is where the mistake would probably be.)
The 2 values I chose were 1000 nm and 500 nm, and they gave 2 different values for the current. Shouldn’t the quantum conductance be in effect in this regime and thus show no difference for a change in a geometry?
Thanks in advance, milz
