This dictates the use of non-visual measurement methodologies to uncover unique chemical and electrical properties. For many of these properties, the actual electrical quantity be- ing measured is a low level current or voltage that is translated to another physical quan- tity. Direct electrical measurements are pos- sible on many nanoscopic substances with probing instruments and nano-manipulators now available. Electrical Property Measurements If a particle becomes small enough, its physical size may approach the wavelength Nanoscale Device & of the material's electrons. Because of quan- tum mechanical effects, the energy of its electrons cannot be predicted by the bonding Material Electrical normally associated with the bulk material. For bulk macroscopic materials, electrons have thermal energies that lie within contin- Measurements
