摘要：

We study the behaviour of the conductance of electrons from finite ordered systems to disordered ones. Strength disorder coupled with the existence of electronic energy relaxation allow us to develop a procedure for increasing the conductance through long linear chains. Our model, which retains some of the basic features of a polypeptide chain, shows the ability of long chains for conveying nanoamp currents. We apply these results for explaining some of the features of STM measurements on bare biological samples. © 1990.
