Coulomb blockade phenomena and quantum fluctuations are studied in mesoscopic\nmetallic tunnel junctions with high charging energies. If the resistance of the\nbarriers is large...
We report low-temperature tunneling measurements through double and triple quantum dots with adjustable interdot tunnel conductance, fabricated in a GaAs/${\mathrm{Al}}_{\mathit...
We report low-temperature tunneling measurements at zero magnetic field through double and triple quantum dots with adjustable interdot coupling, fabricated in a GaAs/AlGaAs het...
We investigate the electron addition spectrum in a class of Hubbard-like models which describe arrays of coupled quantum dots. Interdot tunneling leads to a sequence of two phas...
Individual quantum dots are often referred to as “artificial atoms.” Two tunnel-coupled quantum dots can be considered an “artificial molecule.” Low-temperature measurements wer...
