Flat band analogues and flux driven extended electronic states in a class of geometrically frustrated fractal networks
We demonstrate, by explicit construction, that a single band tight binding Hamiltonian
defined on a class of deterministic fractals of the b= 3N Sierpinski type can give rise to an …
