Chirality effect
WebOct 2, 2002 · We consider chirality related effects in optical, photogalvanic, and electron-transport properties of carbon nanotubes. We show that these properties of chiral nanotubes are determined by terms in the electron effective Hamiltonian describing the coupling between the electron wave vector along the tube principal axis and the orbital … WebChirality is an important spatial property of a single organic molecule, but organic chemists often think about the spatial relationships between two or more molecules as well. For …
