Vertical growth models for analysing vanadium dioxide phase transition in thin films
Vertical growth models for analysing vanadium dioxide phase transition in thin films
Vanadium dioxide (VO2) possesses a metal-insulator phase transition at ~68 °C that is widely explored for nanophotonic and nanoelectronic applications, such as neuromorphic computing and metasurface-based beam steering. In many of these applications, a key challenge is to accurately model the permittivity of VO2 during the phase transition. In this work, we propose vertical growth models for this purpose, and show that they outperform the traditional effective medium models in analysing thin film.

Abstract
Vanadium dioxide (VO2) possesses a metal-insulator phase transition at ~68 °C that is widely explored for nanophotonic and nanoelectronic applications, such as neuromorphic computing and metasurface-based beam steering. In many of these applications, a key challenge is to accurately model the permittivity of VO2 during the phase transition. In this work, we propose vertical growth models for this purpose, and show that they outperform the traditional effective medium models in analysing thin film.
