Electron Transport In Nanowires – An Engineer'S View
In the paper technological problems connected to electron transport in mesoscopic- and nanostructures are considered. The electrical conductance of nanowires formed by metallic contacts in an experimental setup proposed by Costa-Kramer et al. The investigation has been performed in air at room temperature measuring the conductance between two vibrating metal wires with standard oscilloscope. Conductance quantization in units of G o = 2e /h = (12.9 kΩ)−1 up to five quanta of conductance has been observed for nanowires formed in many metals. The explanation of this universal phenomena is the formation of a nanometer-sized wire (nanowire) between macroscopic metallic contacts which induced, due to theory proposed by Landauer, the quantization of conductance. Thermal problems in nanowirese are also discussed in the paper.
