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.
