Effective mobility vs field effect mobility
Webmobility is one of the biggest challenges especially in novel devices such as high-k based MOSFET, III-V devices and SiC power MOSFET etc. Accurate measurement of channel mobility is required for studying the limiting mechanism of mobility. Hall mobility is more favorable than effective mobility or field effect mobility WebAbstract: Effective mobility in top-gated MoS 2 metal-oxide-semiconductor field-effect transistors (MOSFETs) with HfO 2 /TaN gates was investigated. We propose a model for …
