Abstract The sensing capabilities of zinc oxide nano/micro-structures have been widely investigated and these structures are frequently used in the fabrication cutting-edge sensors. However, to date, little attention has paid multi-sensing abilities this material. In work, we present an efficient multisensor based on a single microwire/gold junction. device is able detect real time three different stimuli, UV-VIS light, temperature pH variations. This thanks properties its photoconductive...
Molecular quantum dot cellular automata (MQCA) are among the most promising emerging technologies for expected theoretical operating frequencies (THz), high device densities, and noncryogenic working temperature. Due to small size of an MQCA cell, based on one or two molecules, prototyping even a simple circuit fabrication limited by lack control technological process.
