Abstract
The thermovoltage of a chaotic quantum dot is measured using a current heat ing technique. The fluctuations in the thermopower as a function of magneti c field and dot shape display a non-Gaussian distribution, in agreement wit h simulations using random matrix theory. We observe no contributions from weak localization or short trajectories in the thermopower. [S0031-9007(99) 08804-3].
