1.	Bryllert, Tomas, et al. (författare) Resonant tunneling through coupled self-assembled quantum dots and the influence of inhomogeneous broadening 2002 Ingår i: 7th International Conference on Nanometer-Scale Science and Technology and 21st European Conference on Surface Science. Konferensbidrag (refereegranskat)abstract Resonant tunneling through a single layer of self-assembled quantum dots (QDs) as well as tunneling through two layers of vertically aligned (stacked) dots is investigated. The difference between single and double layers of QDs can be viewed as going from a two-dimensional emitter to a zero-dimensional emitter. By fabricating small-area devices we are able to probe single stacks of quantum dots, revealing details of the coupling between the stacked dots. Very sharp resonances, with peak-to-valley ratios of several hundred, have been measured in the current-voltage characteristics. We also show that the statistical size distribution of self-assembled quantum dots causing the inhomogeneous broadening in luminescence experiments can be analysed in a resonant tunneling experiment
