Web2.4 Variable-Range Hopping In the upper temperature range of hopping conduction, electrons follow the shortest possible path, since the energy penalty in the transition rates or in Equation ( 4) is smaller than the spatial penalty. In this case, conduction is activated. The Hubbard model is an approximate model used to describe the transition between conducting and insulating systems. It is particularly useful in solid-state physics. The model is named for John Hubbard. The Hubbard model states that each electron experiences competing forces: one pushes it to tunnel to neighboring atoms, while the other pushes it away fr…
