NWs, which belongs to the group of ID nanostructures, is characterized by a diameter of 1-100 mn [3]. An important property of NWs is that carriers are only conducted in one dimension; conversely, the two other dime On chip growth of semiconductor metal oxide nanowires for gas sensors a review nsions are quantum confined because of their nanoscale size [4].
