Design and Simulation of Efficient Narrowband Thermal Emitter with 3 µm wavelength

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1473120

A low-power infrared source based on a silicon photonic-crystal membrane has been designed. Temperature distribution and reflection spectrum has been simulated. Large narrowband IR absorption is obtained with optimal material doping....

Studying light-induced degradation by lifetime decay analysis: Excellent fit to solution of simple second-order rate equation

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1056694

Twenty different boron-doped Czochralski silicon materials have been analyzed for light-induced degradation. The carrier lifetime degradation was monitored by an automated quasi-steady-state photoconductance setup with an externally controlled bias lamp for in-situ illumination between measurements....

Characterization of the OSF-band structure in n-type Cz-Si using photoluminescence-imaging and visual inspection

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1026971

Oxygen induced stacking faults (OSFs) are mainly seen in oxygen rich wafers from the seed end of Cz-silicon crystals. In wafers this ring shaped OSF-region delineates a border between two defect regions; usually silicon self-interstitials dominate outside and vacancies inside this ring. High tempera...

Wood's anomalies and spectral uniformity of focusing diffractive optical elements

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+515977

We report on simulations and measurements of focusing diffractive optical elements, fabricated as two-level binary optics. The diffractive optical elements are designed to separate and focus four specific wavelengths in the infrared. The simulations are based on a local linear grating model, and pre...
