Abstract
Scanning tunneling spectroscopy is employed in studies of single InAs nanoc
rystals, 2-8 nm in diameter. The I-V curves exhibit size-dependent charging
and quantum size effects, from which atomic-like states having S and P sym
metries are identified. Excellent agreement is found between level spacings
observed by tunneling and the corresponding optical transitions. (C) 2000
