Microstructural properties of epitaxial CdS, (Cd,Zn)S and CdS ‖ (Cd,Zn)S superlattices

Journal of Crystal Growth, 1992
Abstract Epitaxial CdS, (Cd,Zn)S and CdS ‖ (Cd,Zn)S superlattices have been grown by low pressure MOVPE on (001) and ( 111 )B GaAs substrates. TEM observations have shown that all the epilayers contained irregular arrays of thin planar defects, and higher densities were associated with layers containing higher proportions of Cd and this was ...

LAB ON A CD

Annual Review of Biomedical Engineering, 2006
In this paper, centrifuge-based microfluidic platforms are reviewed and compared with other popular microfluidic propulsion methods. The underlying physical principles of centrifugal pumping in microfluidic systems are presented and the various centrifuge fluidic functions, such as valving, decanting, calibration, mixing, metering, heating, sample ...

Recherches sur le comportement electrochimique des systèmes fondus Cd/Cd Cl2 + Cd/Cd et Cd/Cd Cl2 + KCl + Cd/Cd

Electrochimica Acta, 1963
Resume On a etudie le comportement electrochimique du Cd dans un electrolyte fondu (CdCl2 et CdCl2 + KCl) sature en Cd, dans des systemes symetriques. On a confirme que les processus electrodiques ont lieu sans irreversibilie appreciable. Dans des conditions particulieres d'experience, on a observe du cote anodique, l'intervention de phenomenes de ...

Cd doping at the CuInSe2/CdS heterojunction

Journal of Applied Physics, 2003
The chemical composition of the CuInSe2/CdS heterojunction interface is investigated by angle resolved x-ray photoelectron spectroscopy, Auger electron spectroscopy, and secondary ion mass spectroscopy in combination with selective etching of CdS. We demonstrate that ∼0.8 monolayer of Cd is incorporated into the first 1–3 atomic layers of the CuInSe2 ...

Diffusion of Cd in CdS

Physical Review, 1964
The self-diffusion of Cd in CdS has been measured under a variety of doping and firing conditions. Under saturated Cd pressure the diffusion coefficient is given by $D=3\mathrm{exp}(\ensuremath{-}2.0 \mathrm{eV}/kT)$. Under sulfur pressure at 800\ifmmode^\circ\else\textdegree\fi{}C the diffusion coefficient is found to be linearly dependent on the ...

CdS/InP and CdS/GaAs heterojunctions by chemical-vapor deposition of CdS

Journal of Applied Physics, 1978
CdS/InP and CdS/GaAs heterojunctions were prepared by an in situ H2S/H2 etching process and H2 transport of CdS onto the InP and GaAs substrates. The etching involves a reaction of the III-V compound surface to the corresponding sesquisulfides and simultaneous or subsequent removal by reduction in H2 gas.

Electrical resistivity of liquid Cd-Cu, Cd-Zn and Cd-In systems

Philosophical Magazine, 1972
Abstract The electrical resistivity of liquid Cd-Cu, Cd-Zn and Cd-In systems has been measured from their respective melting points to about 680°c for Cd-Cu and 580°c for Cd-Zn and Cd-In. The nearly free electron theory of liquid alloys proposed by Faber and Ziman is qualitatively in agreement with the results for Cd-Zn and Cd-In, but there are ...

The self-diffusion of Cd in CdS

Journal of Physics C: Solid State Physics, 1984
The self-diffusivity of Cd in CdS, D(Cd), has been measured by a radiotracer technique between 500 and 850 degrees C at the minimum total pressure (pCdmin) and saturated Cd pressure (pCdsat) and also as a function of pCd at 675, 750 and 850 degrees C.
