Inordinate localised systems are used at room temperature in a novel device
in the form of an electron spectrometer for utilising single-electron electronic
applications. Said electron spectrometer device consists of a nanocrystalline metal
or a nanocrystalline semiconductor material used as conductor strip connection
in the form of an inlet or an outlet for single-electron electronic components
and circuits consisting of lithographically produced quantum dots. The resulting
single-electron electronic device consisting of quantum dots is supplied with energetically
very sharply defined electrons. Said device can thus be operated at room temperature,
undisturbed by phonons.
