Ferroelectric field-effect transistors (FeFETs) with multiwall carbon nanotube (MWCNT) micron-wide stripe arrays as channel and (Bi,Nd)4Ti3O12 films as insulator were developed and fabricated. The prepared stripe arrays MWCNT-FeFETs possess excellent properties such as large “on” current, high Ion/Ioff ratio, high channel carrier mobility, and wide memory window. These good performances are mainly attributed to the use of the MWCNT micron-wide stripe arrays channel. The spaces between MWCNT stripes can inhibit the function of the mixed metallic nanotubes in MWCNTs and, thus, improve the semiconductor property of channel layer, and sequentially improve the Ion/Ioff ratio. In addition, the stripe arrays and CNTs within stripes have very high density; therefore, the metallic nanotubes within stripes can transfer many carriers and, thereby, display large “on” current and high channel carrier mobility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
