    • The effect of the substrate or dopants is to transfer some charge to the tube. This modifies the on-site energies which we assume to be known for the two semi-infinite tubes. From this, the additional charge can be easily deduced without the need to perform a self-consistent calculation, if the on-site energies are uniform. At the junction, however, a self-consistent calculation needs to be performed in order to determine the charge and potential profiles, even if the two separated half tubes are treated non-self-consistently.

    • 2DOS(μ). This relation, already explained in the introduction, explains why the real value of the capacitance of a nanodevice is always smaller than its geometrical value.

    • note
    • The exact value of the junction resistance turns out to be very close to its ballistic value due to the small charge accumulation across the junction and the neglect of any disorder. The RC relaxation time is obtained from this exact calculation.
