Influence of Secondary Tip Shape on Illumination-Mode Near-Field Scanning Optical Microscopy Images

August 1, 1999
Author(s)
Lee J. Richter, C E. Dentinger, Richard R. Cavanagh, Garnett W. Bryant, A Liu, Stephan J. Stranick, C D. Keating, M J. Natan
We report illumination-mode near-field optical microscopy images of individual 80-115 nm diameter Au particles recorded with metal-coated fiber probes. It is found that the images are strongly influenced by the metal-coating thickness. This dependence is

Size Dependent Electronic Level Structure of InAs Nanocrystal Quantum Dots: Test of Multiband Effective Mass Theory

August 1, 1998
Author(s)
U Banin, J C. Lee, A A. Guzelian, A V. Kadavanich, A P. Alivastos, Garnett W. Bryant, A L. Efros, M Rose, W Jaskolski
The size dependence of the electronic spectrum of InAs nanocrystals ranging in radius from 10 to 35 Angstrom} has been studied by size-selective spectroscopy. An eight-band effective mass theory of the quantum size levels has been developed which describes
