✦ Synopsis

We investigate silicon-based single-electron transistors in thin layers of highly doped recrystallized amorphous silicon. After rapid thermal annealing polysilicon grains have been found with sizes of about 25 nm acting as electron islands. Applying high-resolution electron-beam lithography we have fabricated nanowires with width down to about 10 nm in the polycrystalline silicon ΓΏlms. Single-electron e ects in the non-linear source-drain characteristics up to temperatures of about 25 K have been observed.

In this work, temperature-dependent measurements of individual In 2 O 3 nanowires were used in order to study the character of the electron transport in these samples. It was found that at low temperatures, the transport was dominated by the electron-electron scattering events. Additionally, the res
