    there is an interesting point. by increasing the net temperature (from 150k to 450k) at a constant channel diameter the on-state current (current at 1V gate field) decreases. what’s your opinion about this device’s behavior?

    In the file dufu1.m, the dummy function for electron density ‘n’ is given as: function y = dufu(x,zeta,delta) y = 1./(1+exp(sqrt(x.2+delta.2)-zeta)) – 1./(1+exp(sqrt(x.2+delta.2)+zeta)); To my deduction, the first term comes out. Where is the second term from? With the integral of density of state D(E) by fermi distribution function f(E), I think it should be like this: y = 1./(1+exp(sqrt(x.2+delta.2)-zeta)); Any clue? Thanks a lot.

    got some error messages

    ??? Error using ==> trapz at 54
    X must be a vector.

    Error in ==> CNTCurrContinuity at 19
    I_continu = (4*q^2/(2*pi*h_bar)).*trapz(myEE_new,Trraspr_new);

    Error in ==> MOSCNT_main at 63
    I_continuity(:,ii_vg,ii_vd) = CNTCurrContinuity(myEE,Trraspr); %% determine current continuity

    Who knows how to solve it?

      I think you may comment all the codes related to \“I_continuity\”, which is not neccessary for ballistic transport.

    Hello When I launch programs MOSCNT; I find a mistake, because it gives me I_continuity =

    Help me to trace the curve ids-VG Please help me Thank you
