Direct laser writing of nanorough cell microbarriers on anatase/Si and graphite/Si

The formation of hierarchical structures consisting of microstripe barriers decorated with nanorough ablated materials prepared by direct laser writing is described. Linear features of circa 25 μm width and 12 μm height are achieved on amorphous and …

Laser heating induced phase changes of VO$_2$ crystals in air monitored by Raman spectroscopy

We have studied the effect of intense visible light on vanadium dioxide crystals in air by measuring micro-Raman spectra for increasing laser powers. A laser wavelength of 632.8 nm was used. For power densities above 500 MW/m2 laser heating triggers …

Laser Heating in Porous Silicon Studied by Micro-Raman Spectroscopy

We have measured the temperature rise in nanoporous silicon under strong illumination. A green laser beam was focused with a microscope objective on porous silicon films with porosities between 55% and 80%. The Raman spectrum was measured for power …

Laser-Assisted Recrystallization to Improve the Surface Morphology of CdTe Epitaxial Layers

Laser-assisted recrystallization has been studied in order to improve the surface morphology of CdTe layers grown on sapphire substrates by metalorganic vapour phase epitaxy (MOVPE). The recrystallization was carried out by scanning the surface of …
