一般說明
Device configuration:
The graphene FET-S20 chip is designed for measurements in liquid medium. This chip provides 12 graphene devices, with encapsulation on the metal pads to avoid degradation and reduce leakage currents, and the probe pads located near the periphery of the chip. It also includes a non-encapsulated electrode at the center of the chip, which allows liquid gating without the need of an external gate electrode.
