Design and Characterisation of VO2 Based Switches for Ultra-Fast Reconfigurable Devices

Mott transition materials seem particularly promising to design reconfigurable devices. In this paper, Vanadium Dioxide (VO
₂
) is studied and characterized to design switches and elementary RF devices. The study shows experimentally promising RF performances under electrical control and also for an optical excitation of the VO
₂
with ultra-short switching time. These results put forward the use of VO
₂
switches as a core function to design ultra-fast purpose RF devices dedicated to future military and civilian standards.
