Effects of gamma irradiations on reactive pulsed laser deposited vanadium dioxide thin films

Young’s modulus of pulsed-laser deposited V6O13 thin films

The mixed valence vanadium oxide V6O13 is an interesting material which exhibits an insulator-to-metal or semiconductor-to-semiconductor transition at low temperatures. It is also a much studied cathode material for lithium-based thin film batteries. However, there is little information available about its mechanical properties. Young’s modulus of pulsed-laser deposited V6O13 thin films has bee...

Pulsed laser deposited GeTe-rich GeTe-Sb2Te3 thin films

Pulsed laser deposition technique was used for the fabrication of Ge-Te rich GeTe-Sb2Te3 (Ge6Sb2Te9, Ge8Sb2Te11, Ge10Sb2Te13, and Ge12Sb2Te15) amorphous thin films. To evaluate the influence of GeTe content in the deposited films on physico-chemical properties of the GST materials, scanning electron microscopy with energy-dispersive X-ray analysis, X-ray diffraction and reflectometry, atomic fo...

Structural and electro-optic properties of pulsed laser deposited Bi4Ti3O12 thin films on MgO

Ferroelectric Bi4Ti3012 thin films have been grown on MgO ( 100) and MgO( 110) substrates by the pulsed laser deposition. X-ray diffraction studies show that the films on both substrates have preferential crystallographic orientation such that most of their c axes are close to the substrate normal direction. The film on MgO( 110) shows quadratic and hysteretic electro-optic characteristics with...

Pulsed Laser Porosification of Silicon Thin Films

We present a new and simple laser-based process to porosify thin film silicon using a pulsed laser. During deposition, we incorporate gas atoms or molecules into the Si thin film. Pulsed laser radiation of wavelength λ = 532 nm heats up thin film Si beyond its melting point. Upon heating, gas atoms or molecules form nm-sized thermally expanding gas bubbles in the silicon melt, until they explos...
