Thermal expansion coefficient of hydrogenated amorphous carbon

The coefficient of thermal expansion ~CTE! of hydrogenated amorphous carbon (a-C:H) was investigated as a function of the concentration of sp hybridization. The CTE, determined using the thermally induced bending technique, depends on the concentration of sp bonded carbon, increasing to the value of graphite as the sp concentration approaches 100%. By using a combination of the thermally induce...

On the Determination of Thermal Expansion Coefficient of Thermal Oxide

The accurate value of thermal expansion coefficient ( ) of thin film is an important thermal property in the design of microelectronic devices and microsystem. This research presents a microbridge buckling deformation caused by the residual stresses to determine the of thermal oxide (SiO2) film. The extraction of is supported through experimental means and finite element analysis (FEM) of the b...

Effect of Variable Thermal Expansion Coefficient and Nanofluid Properties on Steady Natural Convection in an Enclosure

Steady state natural convection is numerically investigated in an enclosure using variable thermal conductivity, viscosity and thermal expansion coefficient of Al2O3–water nanofluid. This study has been conducted for a wide range of Rayleigh numbers (103≤ Ra ≤ 106), concentrations of nanoparticles (0% ≤ Φ ≤ 7%), enclosure aspect ratios (0.5 ≤ AR ≤ 2) and temperature differences between the cold...
