transmission values

[ramkrishna]

Dear Sir,
     I was looking the tutorial " http://quantumwise.com/documents/tutorials/latest/Fe-MgO-Fe/index.html/chap.mgo.anti.html " for the transmission spectrum/k-resolved transmission. However, I found that in the transmission spectrum the value is in the order of 10^-6 but in k-resolved, it is showing the maxima in the order of 10^-4. So, I am quite confused why the values in k-resolved is high with respect to the value from the trans. spectrum? If you will discuss this issue, it will be very much helpful to understand the transmission plot.

Thanks
Ramkrishna

The total T(E) is the integral over kx,ky of T(E,kx,ky). It's not strange that the integral of a function is less than the individual values of the function in (typically small) regions. Take the integral of f(x)=exp(-100x) from 0 to 1. The function value at x=0 is f(0)=1 but the integral is about 0.01.

Thanks a lot, I got it.
