(a) curves of an orthorhombic peptide NW at various temperatures [102]. (b) The averaged of FF and FW peptide nanodots [103]. (c) Calculated molecular orbital amplitude plots and energy levels of the highest occupied and lowest unoccupied molecular orbitals of cyclo-FW and cyclo-WW, showing band gaps of 3.63 eV and 3.56 eV, respectively [105]. (d) Projected DOS for FF (top), YY (middle), and FW (bottom) nanotubes [106]. (e) Scanning electron microscopy image of the actual device (scale bar: 2 μm). (Inset) Current-voltage curve of the silver-seeded silver nanoribbon [115].
