Ultrafast 27 GHz cutoff frequency in vertical WSe2 Schottky diodes with extremely low contact resistance
Two-dimensional materials show promise for 5G wireless communication applications. Here, the authors report vertical Schottky diodes based on thick mechanically exfoliated WSe2 flakes having low ohmic contact resistance of 50 Ω and ultrafast cutoff frequency of 27 GHz.
