Localization in Artificial Disorder - Two Coupled Quantum Dots
M. Brodsky, N. B. Zhitenev, R. C. Ashoori +2
Using Single Electron Capacitance Spectroscopy, we study electron additions in quantum dots containing two potential minima separated by a shallow barrier. Analysis of addition spe…

The Localization-Delocalization Transition in Quantum Dots
N. B. Zhitenev, M. Brodsky, R. C. Ashoori +2
Single-electron capacitance spectroscopy precisely measures the energies required to add individual electrons to a quantum dot. The spatial extent of electronic wavefunctions is pr…

A New Class of Resonances at the Edge of the Two Dimensional Electron Gas
N. B. Zhitenev, M. Brodsky, R. C. Ashoori +1
We measure the frequency dependent capacitance of a gate covering the edge and part of a two-dimensional electron gas in the quantum Hall regime. In applying a positive gate bias,…
