Abstract [en]

We present a detailed analysis of hot-carrier degradation (HCD) in graphene field-effect transistors (GFETs) and compare those findings with the bias-temperature instability (BTI). Our results show that the HCD in GFETs is recoverable, similar to its BTI counterpart. Moreover, both the degradation mechanisms strongly interact. Particular attention is paid to the dynamics of HCD recovery, which can be well fitted with the capture/emission time (CET) map model and the universal relaxation function for some stress conditions, quite similar to the BTI in both GFETs and Si technologies. The main result of this paper is an extension of our systematic method for benchmarking new graphene technologies for the case of HCD.
