Universal fluctuations of Coulomb blockade peaks in quantum dots

Year: 1997

Type: article

Abstract: We describe recent measurements of the statistics and parametric correlations of Coulomb blockade peak heights in shape-deformable GaAs/A1xGa1−xAs quantum dots. We find good agreement between the measured distributions of peak heights and probability distributions predicted by random matrix theory for bothB= 0 andB≠ 0. The measured magnetic flux correlation lengthϕcis of the order of but less than one flux quantum through the dot,ϕc∼ 0.8ϕ0, inconsistent withϕcpredicted by universal scaling theory for isolated chaotic quantum dots.
