Abstract
The thermovoltage of a chaotic quantum dot is measured using a current heating technique. The fluctuations in the thermopower as a function of magnetic field and dot shape display a non-Gaussian distribution, in agreement with simulations using random matrix theory. We observe no contributions from weak localization or short trajectories in the thermopower.
