1/f Tunnel Current Noise through Si-bound Alkyl Monolayers
Preprint
- 6 March 2010
Abstract
We report low frequency tunnel current noise characteristics of an organic monolayer tunnel junction. The measured devices, n-Si/alkyl chain (C18H37)/Al junctions, exhibit a clear 1/ f^y power spectrum noise with 1< y 0.4 V, with an amplitude varying from device to device. We attribute this effect to an energy-dependent trap-induced tunnel current. We find that the background noise, SI, scales with (\partial I/\partial V)^2 . A model is proposed showing qualitative agreements with our experimental data.Keywords
