Hybrid molecular electronic (HME) transistor based on deoxyguanosine derivatives

摘要

In this work,a field effect transistor based on deoxyguanosine derivatives (a DNA basis)is demonstrated by means of systematic transport experiments. Our nanodevices were fabricated starting from a deoxyguanosine derivative (dG(C_(10))_2) layer interconnecting planar nano-electrodes,with separation in the 20-40nm range. The three terminal devices exhibit a maximum voltage gain of 0.76. Though the quick aging and the reproducibility of the devices have to be improved, the realization of a transistor-like device represents a starting point towards the development of planar solid-state bio-molecular electronic devices.
