Room-temperature conductance spectroscopy of CdSe quantum dots using a modified scanning force microscope

摘要: The conductance of isolated CdSe quantum dots (QD's) \ensuremath{\sim}4 nm diameter, epitaxially electrodeposited on gold substrates, has been studied using a scanning force microscope with metallized tip to perform current-voltage spectroscopy. band gaps the have measured and correlated QD size distribution. Reproducible peaks in room-temperature spectra are interpreted as transport single electrons through dots. roles both Coulomb charging interlevel spacing considered.
