Abstract :
In this study, we have numerically examined the effect of applied bias on the transmission across Dimer Fibonacci Height Barrier Superlattices (DFHBSL) by using the exact airy function formalism and the transfer matrix technique. We have observed the formation of miniband structure and disappearance of the singularly localised states in the Structure of Dimer Fibonacci in height barrier superlattices (DFHBSL), Its due to the interaction between the states of the dimer wells inside the potential, the electron sees the system like two structure ordered imbricate one in the other, therefore, one tends more towards the order than the disorder related to the structure of Fibonacci.
