We investigate the transport characteristics of Ge/Si-Core/Shell nanowirewith Coulomb Blockade in presence of external magneto-electric fields from atheoretical basis. Using the effective Luttinger-Kohn Hamiltonian we calculatethe valence band energy states of the nanowire and find out the state densityat mili-Kelvin temperature. We explore the current-voltage andconductance-voltage characteristics. The observed transport characteristics arein close agreement with experimental data. We find these characteristics to besensitive to the coupling of the quantum dot with the reservoirs. The quantumnature of the characteristics becomes less prominent with increasingtemperature, as expected.
