Investigation of hydrogen implantation-induced blistering phenomenon in Si0.7Ge0.30

The blistering phenomenon in hydrogen implanted and annealed Si0.70Ge0.30(0 0 1) layers was investigated. The implantation was performed with 240 keV H2 + ions with a fluence of 5 × 1016 cm−2. The blistering...

Quantitative phase and refractive index measurements with point-source digital in-line holographic microscopy

Point source Digital In-line Holographic Microscopy with numerical reconstructio is ideally suited for quantitative phase measurements to determine optical path lengths and to extract changes in refractive...

Generation of high quality, 1.3 cycle pulses by active phase control of an octave spanning supercontinuum

Nonlinear pulse compression based on the generation of ultra-broadband supercontinuum (SC) in an all-normal dispersion photonic crystal fiber (ANDi PCF) is demonstrated. The highly coherent and smooth...

Identification of primary tumors of brain metastases by Raman imaging and support vector machines

Vibrational spectroscopic imaging techniques are new tools for visualizing chemical components in tissue without staining. The spectroscopic signature can be used as a molecular fingerprint of pathological...

Raman and FTIR Microspectroscopy for Detection of Brain Metastasis

Vibrational spectroscopic imaging methods are novel tools to visualise chemical component in tissue without staining. Fourier transform infrared (FTIR) imaging is more frequently applied than Raman imaging...

Core-shell heterojunction solar cells on silicon nanowire arrays

Highly efficient core-shell TCO/a-Si/Si nanowires (SiNWs) heterojunction solar cells were fabricated on SiNW arrays prepared by metal assisted wet chemical etching of an n-type silicon wafer. The silver...

Magnetic domain wall pinning by kinks in magnetic nanostripes

We report a combined micromagnetic and experimental study dealing with the influence of the nanostripe geometry on the domain wall (DW) pinning at kinks in nanostripes. For both, the experiments as well...
