We report electrical and optoelectrical properties of a cross-junction of two semiconducting nanowires. Semiconducting nanowires and their junction play an important role in nanonetwork device. By mechanically manipulating the nanowires, cross-junction nanodevices are fabricated on SiO2/Si substrate using VO2 and ZnO nanowires. These junctions are formed across prepatterned two-probe Au electrodes and contacted through Pt metal deposition. The cross-junction devices were studied using global and focused laser beam irradiation with a wavelength of 532 nm at sweeping bias and fixed external bias. Furthermore multi-junction in nanonetwork between VO2 and ZnO nanowires device is demonstrated as a viable photodetector for potential application.

We demonstrate a solid-state spiking artificial neuron based upon an insulator-to-metal (IMT) transition material element that operates at an unprecedented low voltage (0.8 V). We have developed a general coupled electrical-thermal device model for IMT based devices to accurately predict experimental outcomes. From the experiment and simulation, we show that voltage scalability to sub 0.3 V is possible by scaling of the IMT based neuron.
