This part of IEC 62607 specifies a measurement protocol to determine the key control characteristic
activation energy of electronic trap states
for metal-oxide interfacial devices by
low-frequency-noise spectroscopy
The noise spectra peak temperatures are obtained within a designated temperature range.
Activation energies are then calculated based on the frequency dependence of the peak temperatures to
analyse the energy levels associated with the electronic trap states. The activation energy is determined by the temperature dependence of the capture time at electron traps
under the assumption that it is described by an Arrhenius function.
In metal-oxide interfacial devices, electrical conductance is observed through an oxide nanolayer sandwiched between
metal electrodes.
The size of the conductive path in metal-oxide interfacial devices is dependent on the current value and is usually nanoscale in diameter, taking the
form of a filamentary wire. This evaluation method is useful for analysing the electronic trap states in nanowires and other miniaturized devices that have na...
