The field-emission phenomenon is exploited in a broad variety of applications and systems. Previous studies have reported that the current induced by field emission strongly and inherently depend on the temperature. This dependence enhances the noise

There is a strong non-linearity between the field-emission current amplitude and field intensity. This nonlinearity degrades the dynamic range of digital signal processing in a mechanical oscillator composed of a cantilever. To solve this issue, we p

In field emission-based nanoelectromechanical systems (NEMSs), there is a strong nonlinearity between the amplitude of the field emission current signal and the field intensity of the incoming signal. This nonlinearity degrades the dynamic range and
