Design and Characterisation of VO 2 Based Switches for Ultra-Fast Reconfigurable Devices

International audienceMott transition materials seem particularly promising to design reconfigurable devices. In this paper, Vanadium Dioxide (VO2) 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 VO2 with ultra-short switching time. These results put forward the use of VO2 switches as a core function to design ultra-fast purpose RF devices dedicated to future military and civilian standards
