Oxide semiconductor thickness dependence of a CoOx/IGZO/CoOx selector.

(a) I-V responses of p-n-p selectors containing 5-, 7-, 9- and 11-nm-thick IGZO layer with a 5-nm-thick CoOx p-type oxide semiconductor. (b) On/off ratios of each selector recorded at Vread and Vread/2. (c) I-V features of 5, 10, 15 thick CoOx with a 5-nm-thick IGZO n-type oxide semiconductor. (d) On/off ratio of each selector taken at Vread and Vread/2.
