Experimental results gained by various electrical characterization techniques are discussed and compared for a CNTFET technology, which suffers as almost all emerging technologies from traps in the gate oxide. Based on these results, it is highlighted that, contrary to common practice, a fast data acquisition technique is required to ensure a proper electrical device characterization in terms of (i) trap-free device characteristics, (ii) reproducible experimental results and (iii) a consistent set of DC and small-signal (AC) characteristics. It is argued that a reasonable technology comparison among emerging technologies must be based on data fulfilling these criteria since trap-affected measurements distort the device behavior which can lead to wrong conclusions about the performance of a device such as the apparent linearity. A trap model capturing the above mentioned issues is briefly introduced. Moreover, the challenges of the electrical characterization of high-impedance devices are explored.
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.
