We propose and experimentally demonstrate top-gated complementary n- and p-type black phosphorous FETs by engineering the workfunction of pre-patterned electrodes embedded in a SiO2 layer. Pre-patterned electrodes offer the possibility of reducing the exposure time of exfoliated flakes to oxidant agents with respect to top-contacted devices and maximize the accessible area for sensing applications...
This work presents one of the first low power pH sensing microfluidic chip based on the heterogeneous integration of: (i) high-k FinFET sensors with liquid gate, (ii) miniaturized Ag/AgCl quasi-Reference Electrode and (iii) passive microfluidic. The integration of these three components provides a fully integrated and compact platform that could be exploited for ionic monitoring in biofluids for healthcare...
This paper reports the fabrication of conductance-based gas sensors based on horizontal, dense carbon nanotube (CNT) arrays directly integrated between metal electrodes via a selective and directional catalytic growth process performed insitu and at the wafer-scale. We originally propose to use a functionalization strategy focusing on the key role of the electrode-CNT junction, for increased selectivity...
For the first time, self-aligned suspended-body carbon nanotube field-effect-transistors (CNTFETs) with efficient and independent electrostatic control by two laterally placed independent gates spaced less than 100 nm away from the CNT channel have been demonstrated. A precise positioning method using resist trenches is used for their fabrication. A superior control of I–V characteristics by two lateral...
