Role of Working Temperature and Humidity in Acetone Detection by SnO Covered ZnO Nanowire Network Based Sensors.

A randomly oriented nanowire network, also called nanonet (NN), is a nano-microstructure that is easily integrated into devices while retaining the advantages of using nanowires. This combination presents a highly developed surface, which is promising for sensing applications while drastically reducing integration costs compared to single nanowire integration. It now remains to demonstrate its effective sensing in real conditions, its selectivity and its real advantages.

AlO, Al doped ZnO and SnO encapsulation of randomly oriented ZnO nanowire networks for high performance and stable electrical devices.

Two-dimensional randomly oriented nanowire (NW) networks, also called nanonets (NNs), have remarkable advantages including low-cost integration, good reproducibility and high sensitivity, which make them a promising material for electronic devices. With this work, we focus on the study of ZnO NNs as channel materials in field effect transistors (FETs). In our process, ZnO NWs were assembled in NNs by the liquid filtration method and were integrated in transistors, with the bottom-gate configuration, using simple technological steps.

High performances, temperature resistant and stable OLED structures.

In the present work, a particular emphasis is put on the stability of the OLED devices obtained as well as on their ability to keep their good initial performances even in a severe environment. Moreover, the operation voltage of these devices turns out to be rather low.
