Photoconductivity of Selenium and Sulphur Doped a-Si:H thin Films
Se S a-Si:H Photoconductivity recombination mechanism
2010/4/12
This paper presents a study of photoconductivity of S- and Se-doped a-Si:H as a function of composition and temperature. Temperature dependence of photoconductivity of the films was measured under the...
Single Si d-Doped GaAs Investigations by New Photothermal Wavelength Modulated Photocurrent Technique
Photothermal Wavelength Modulated Photocurrent
2010/4/16
New Photothermal Wavelength Modulated Photocurrent (PWMPC) technique is reported. This technique is used for investigation of the MBE grown p-GaAs sample in which a single Si-layer was embedded with a...
Determination of Optical Constant of Materials by two Different Methods: An Application to Single Crystals Si
Optical Constant Si Single Crystals Oscillator Fit Procedure Kramers-Kronig Analysis
2010/4/15
The normal reflectance of single crystal Si was measured at 0.5 ­5.6 eV range by unpolarized light. Optical parameters of Si were determined from this reflectance data by using two different metho...
