Abstract
Molybdenum disulfide (MoS 2 ), a member of the transition metal dichalcogenide (TMD) family, is a 2D semiconductor with a direct bandgap of ∼1.8 eV for single layers. Its bandgap allows for high I on /I off metal-oxide semiconducting field-effect transistors (FETs). Exfoliated monolayer MoS 2 FETs exhibit current saturation with on-state current densities of 300 µA/µm, as well as transconductances exceeding 40 µS/µm [1]. These properties make MoS 2 a desirable candidate for radio frequency (RF) applications [1, 2, 3]. However, in order for MoS 2 devices to move from laboratory experimentations to industrial scale applications, large area synthesis of high quality material is needed. Here we demonstrate gigahertz RF performance and circuits (amplifier and mixer) using chemical vapor deposited (CVD) monolayer MoS 2 FETs.
