Enhancing Modulation of Thermal Conduction in Vanadium Dioxide Thin Film by Nanostructured Nanogaps

Characterization of nanostructured SnO2 thin film coated by Ag nanoparticles

Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...

Temperature-Dependent Femtosecond Pump-Probe Spectroscopy of Thin-Film Vanadium Dioxide

Vanadium dioxide (VO2) is characterized as a transitional-metal oxide that undergoes an abrupt insulator-to-metal phase transition upon a threshold-crossing external stimulus such as heating above a critical temperature of ~344 K, applying a sufficient electric field, or optical excitation above a threshold fluence. In this thesis, temperature-dependent, degenerate femtosecond pump-probe spectr...

Thin-Film Flow Influenced by Thermal Noise

We study the influence of thermal fluctuations on the dewetting dynamics of thin liquid films. Starting from the incompressible Navier-Stokes equations with thermal noise, we derive a fourth-order degenerate parabolic stochastic partial differential equation which includes a conservative, multiplicative noise term—the stochastic thin-film equation. Technically, we rely on a long-wave-approximat...
