We have obtained a hole mobility for the organic conductor pentacene of 35 cm2/Vs at room temperature increasing to 58 cm2/Vs at 225K. These high mobilities result from a purification process in which 6,13-pentacenequinone was removed by…

Here, we present a temperature ($T$) dependent comparison between field-effect and Hall mobilities in field-effect transistors based on few-layered WSe$_2$ exfoliated onto SiO$_2$. Without dielectric engineering and beyond a $T$-dependent…

The field-effect mobility of graphene devices is discussed. We argue that the graphene ballistic mean free path can only be extracted by taking into account both, the electrical characteristics and the channel length dependent mobility. In…
