Is screening length in tunneling probability equation actually the tunneling barrier length?

Drain current of a TFET is proportioned to tunneling probability Tt. As it can be seen from the picture, Λ is screening length. my question is that can we call Λ, "tunneling barrier length/width" or not? there is a lot of names for Λ, however non of them is barrier length.
