A deeper study of the effect of metal interlayer thicknesses on the work function and its relationship with Fermi energy level is in progress.
By taking the approximation that [N.sub.A] equals to hole density and that the effective mass of the hole in [Cu.sub.2]O is 0.58 [m.sub.0] [21], the Fermi energy position of Sample 2 was found to be 0.9 eV above the valance band maximum.
As [O.sub.2] adsorption on a SWNT surface could shift the position of Fermi energy [30] and complicate the analysis, the sample was preannealed in Ar to eliminate possible molecular adsorption [13].
Where m* is the band-edge effective mass, k is Boltzmann constant, T is the lattice absolute temperature, h is Plank constant divided by 2, Tu* Tu gives the tunneling probability density of the outgoing electron, F is Fermi energy level, l is energy of the electron associated with longitudinal wave vector of the electron in the conduction band, V is the applied voltage.
The existence of populated electronic states near the Fermi energy level on the eDOS (Eq.
This is because, at lower temperatures, most of the fermions are yet to surpass the barrier created by the Fermi energy and hence are all restricted to the lower end of the energy.
At this quirky dimension, the chemical potential of both, the Fermi and Bose ideal gases, decreases monotonically with temperature essentially in the same functional way [54], being different only by an additive constant, expressly, the Fermi energy. This results in the same temperature dependence of their respective specific heats at constant volume [C.sub.V] [54-56].
In this paper we find out the basic solid state parameters like penn gap, plasma energy, polarizability and fermi energy for calcium boro lactate crystals.
At the metallization pressure, the values for density of states at Fermi energy N([E.sub.F]) are very small (pseudo gap), which indicate that metallization has just set in CdO (Fig.4).
Due to the Pauli's exclusion principle, only the electrons with energies which are close to the Fermi energy participate in the conduction phenomena.
The dotted line in Figure 1 represents the zero-point energy of the Fermi energy level.
However, it is found that, as a result of insertion of Li, its HOMO-LUMO gap reduces further from 0.326 to 0.143 eV, and therefore it is expected that it should have a higher equilibrium conductance (i.e., transmission coefficient at the Fermi energy of the system).
