Extreme Ultraviolet Transient Grating Measurement of Insulator-Metal Transition Dynamics in VO2
نویسندگان
چکیده
We demonstrate spectrally resolved transient grating (TG) spectroscopy in the extreme ultraviolet (EUV) near the M-edge of vanadium dioxide. Timedependent and broadband EUV-TG measurements separate the index of refraction change due to the insulator to metal transition from purely acoustic effects.

Broadband extreme ultraviolet probing of transient gratings in vanadium dioxide.
Nonlinear spectroscopy in the extreme ultraviolet (EUV) and soft x-ray spectral range offers the opportunity for element selective probing of ultrafast dynamics using core-valence transitions (Mukamel et al., Acc. Chem. Res. 42, 553 (2009)). We demonstrate a step on this path showing core-valence sensitivity in transient grating spectroscopy with EUV probing. We study the optically induced insu...
متن کاملStudying the Ultrafast Dynamics of the Insulator-Metal Transition in Single Crystal VO2
The focus of my research project this summer was towards the investigation of the insulatormetal transition dynamics of vanadium dioxide. A summary of the currently known, as well as debated, properties of the material is given here. Also given are the various experimental details involved in the measurements. We used femtosecond pulses in pump-probe experimentation to achieve time-resolved ref...
متن کاملElectrodynamics of the vanadium oxides VO2 and V2O3
The optical and infrared properties of films of vanadium dioxide VO2 and vanadium sesquioxide V2O3 have been investigated via ellipsometry and near-normal incidence reflectance measurements from far infrared to ultraviolet frequencies. Significant changes occur in the optical conductivity of both VO2 and V2O3 across the metal-insulator transitions at least up to and possibly beyond 6 eV. We arg...
متن کاملSubstrate-induced microstructure effects on the dynamics of the photo-induced metal–insulator transition in VO2 thin films
We investigate the differences in the dynamics of the ultrafast photo-induced metal–insulator transition (MIT) of two VO2 thin films deposited on different substrates, TiO2 and Al2O3, and in particular the temperature dependence of the threshold laser fluence values required to induce various MIT stages in a wide range of sample temperatures 150–320 K. We identified that, although the general p...
متن کاملTemperature-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...
