We nd that the narrow

density of states of N- doped GNRs and the bias-dependent effective coupling between the discrete frontier molecular orbitals and the subbands of electrodes are responsible for the observed NDR behavior.

3 illustrates the

density of state (DOS) which plays an important role in various physical systems where HOMO and LUMO are shown by green and blue lines, respectively and region between green and blue lines represents the energy gap.

Figure 2 shows a

density of states projected onto both crystal momentum component k parallel to the edge and the distal row of edge atoms.

Thus, knowing the

density of states allows researchers to select and manipulate materials to create useful devices.

In terms of a four-band model for room temperature n-type GaSb, the total

density of states [[rho].

Following up on this line of investigation, we suggest the possible origins of a low

density of states within HOMO-LUMO gap using model calculations.

Appendices address Poisson statistics, parametric amplification, the

density of states, low-dimensional semiconductor structures, nuclear magnetic resonance, and Bose-Einstein condensation.

Electrical measurements on nanoscale materials and devices reveal not only electronic characteristics, but also general properties like a nanoscopic particle's

density of states.

c] is the

density of states for the conduction band, [[rho].

Density of States and Local Barrier Height

From knowledge of the

density of states (15) and calculations of the energy band structure (16), they were able to prove theoretically and to confirm experimentally that this semiconductor becomes a superconductor, albeit at only 0.

The scientists say the configuration is well suited for reducing threshold current in blue lasers, since wide bandgap materials have large optical gain due to the giant joint

density of states.
