Is screening length in tunneling probability equation actually the tunneling barrier length?
Closed  Responses: 0
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...

Tunneling
30 Jul 2011  Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This set of slides describes the quantummechanical process for tunneling and how it is accounted for in modeling semiconductor devices. We explain WKB approximation, transfer matrix approach and the TsuEsaki formula for the calculation of the current.
