Research Plan • How design affects a sensitivity • Model a gaspenetrationinto a 3D gas sensor • Set a conductivityof Niobium oxides • Model currentflow inthe3D gas sensor • Measure real samples from Sasha • Analyse obtained data Investice do rozvoje vzdělávání
Current DefinitionwithPerforatedElectrode Distance between pillars = 108 nm will be changed to 125 nm (all the dimensions in nanometers) dpillar = 60 nm sample for simulation = 5 m x 5 m => npillars ≈ 2500
