Abstract
It is demonstrated that localized states of an open quasi-one-dimensional q uantum dot can be charged by the Coulomb blockade mechanism. A new effect-C oulomb oscillations of the ballistic conductance-is observed because of the high sensitivity of the ballistic current to single-electron variations of the self-consistent potential of the dot. The model proposed explains expe rimental results [C.-T. Liang, M. Y. Simmons, C. G. Smith, et al., Phys. Re v. Lett. 81, 3507 (1998)]. (C) 2001 MAIK "Nauka/Interperiodica".
