Title: Final report

Conductivity and Magnetism in Strongly Coupled Quantum Dot Solids. One outcome of the project is the discovery of a rather universal 1/f noise magnitude in electrical transport across nanocrystals. The noise is extensive in the number of dots in the device, and inversely proportional to the interdot resistance. The other outcome is a study of the magneto-resistance of light and heavy doped chalcogenides semiconductor quantum dots with Manganese. Strong MR was observed at low temperature in n-doped Mn doped quantum dot films, and this was attributed to the formation of magnetic polarons.
