Abstract
Growth of monolayer single-crystalline graphene using low pressure chemical vapor deposition (LPCVD) method is reported. Radio frequency (RF) nano switches based on coplanar waveguide double-clamped single-crystalline graphene membrane was achieved for the first time. Owing to the single crystalline nature, its life time (> 5000 times) is much longer than polycrystalline graphene (PCG) switches (4-5 times [1]). It exhibits small pull-in voltage (∼1 V) and superb signal isolation (c30 dB at 40 GHz) which can be further improved by graphene's unique electric field effect.
