Quantum dot from chiral metallic single walled nanotubes

الأصل · EN

We propose a simple approach to construct a quantum-dot and it's electrodes using chiral metallic single walled carbon nanotube (CM-SWCNT) segments of exactly opposite chiralities (m,n) and (n,m). The degree and energetics of electron confinement crucially depends on the choice of n and m, and collinearity of the SWCNT segments constituting the quantum-dot and the electrodes. All the segments can in principle be obtained through simple manipulations of fragments of a single nanotube of chirality either (m,n) or (n,m).
