The electronic spectral and transport properties of aperiodic quantum dot chains are investigated. The systems with singular continuous energy spectrum are considered: Thue–Morse chain, double-periodic chain, Rudin–Shapiro chain. The influence of electronic energy in quantum dot on the spectral properties, band structure, density of states and spectral resistivity, is discussed. Low resistivity regions correspond to delocalized states and these states could be current states. Also we discuss the magnetic field application as the way to tune electronic energy in quantum dot and to obtain metallic or insulating conducting states of the systems.
► We show the influence of electronic energy in quantum dot on the localization degree of electrons at the Fermi energy. ► The method to tune electronic energy in quantum dot by application of relatively small magnetic field is proposed. ► This method allows to obtain metallic or insulating conductive properties of aperiodic chain of quantum dots.
