Non-contacting measurements of photocarrier lifetimes in bulk- and polycrystalline thin-film Si photoconductive devices by photothermal radiometry
(1996)Laser-induced and frequency-scanned infrared photothermal radiometry was applied to a crystalline-Si photoconductive device, and to polysilicon thin-film photoconductors deposited on oxidized Si substrates by an LPCVD ...

Optical and structural properties of implanted Si wafers: the effects of implantation energy and subsequent isochronal annealing temperature
(2006)We have studied the influence of implantation energy and subsequent isochronal annealing temperature on the optical and structural properties of implanted Si wafers employing a multiwavelength spectroscopic ellipsometer. ...

Photomodulated thermoreflectance investigation at elevated temperatures: plasma versus thermal effect
(2003)Photomodulated thermoreflectance measurements were performed at elevated temperatures (294 to 623 K), on crystalline silicon lightly doped with boron. The temperature dependence is qualitatively and quantitatively discussed. ...

Photothermal hydrogen sensor: the technique, experimental process, and physicochemical analysis
(2008)The kinetics of hydrogen adsorption and desorption on palladium thin films was studied via photomodulated thermoreflectance measurements. The subsequent analysis based on a Langmuirian isothermal model supports dissociative ...

Thermoelectronic-wave coupling in laser photothermal theory of semiconductors at elevated temperatures
(1997)A quantitative analysis of linear temperature-dependent coupled thermoelectronic diffusion waves in the generation of the laser-induced IR photothermal radiometric signal from a photoexcited, plasma-wave-dominated, ...

Two layer model for photothermal radiometry applied on semiconducting thin films
(1997)A two layer model has been developed in order to study the dependence of the photothermal radiometric signal on the optoelectronic and thermophysical properties of a two layer semiconducting sample. In the following ...

Two-layer model for photomodulated thermoreflectance of semiconductor wafers
(1996)A complete theoretical analysis of the laser photomodulated thermoreflectance signal from a two-layer semiconducting wafer is presented. It is shown that the electronic and thermal properties of a thin surface layer may ...
