Photoacoustic Technique for Thermal Conductivity and Thermal Interface Measurements
The photoacoustic (PA) technique is one of many techniques for characterizing thermal conductivity of materials, including thermal interface conductance or resistance. Compared with other techniques, the PA method is relatively simple, yet is able to provide accurate thermal conductivity data over a wide range of materials and properties. In the last decade, the PA method has been developed and...
متن کاملDetermination of porous Silicon thermal conductivity using the “Mirage effect” method
Mirage effect is contactless and non destructive method which has been used a lot to determine thermal properties of different kind of samples , transverse photothermal deflection PTD in skimming configuration with ccd camera and special programs is used to determine thermal conductivity of porous silicon ps film. Ps samples were prepared by electrochemical etching. Thermal conductivity wit...

متن کاملPhotoacoustic effects in nanocomposite structure ‘porous silicon-liquid’
Photoacoustic effect in nanocomposite structure 'porous silicon-liquid' has been investigated. Main mechanisms involved in the formation of photoacoustic signal in such structures have been experimentally studied. Liquids with different viscosity (ethanol and acetone) filling the nanopores have been used. A proposed mathematical model describing the photoacoustic signal formation was found to b...
