It is thus a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across the material.
For semiconductor materials the coefficient may be between 100μV/°K and 300μV/°K, in any case still very small.
The Seebeck voltage does not depend on the temperature distribution along the conductor but only on the temperature difference between the ends For comparison purposes the usefulness of thermoelectric materials for electricity generation as well as for heating and cooling can be characterized using a figure of merit incorporating these properties.
The figure of merit Z of a thermoelectric material is a measure of its efficiency as an energy conversion component and is defined as : Z = Σs2/ λ (2) Materials with high thermoelectric figures of merit are typically heavily doped semiconductors and for many years the best materials had a figure of merit of around 1.
Recent advances in materials science have increased this number to around 4.

The viscous behavior of the adhesive material and thermal mismatch between the dissimilar materials in the package were considered.
In a thin package, the coefficient of temperature expansion (CTE) mismatch between different materials is regarded as the main reason for warpage.
In order to save computational cost, 1/4 of the package with 64 joints (Fig.2) was investigated based on the geometrical dimensions and materials properties described in Jung's work [5].
Also, high stresses usually appear after several thermal cycles due to the creep behavior of the adhesive and solder materials.

These observations suggested that the quantity and size of ablated materials depended on the pulse power and the confinement effects of the liquid.
The ablated materials appeared during the laser ablation need four stages to perform [4].
Dispersed materials can be nanoparticles, small clusters, free atoms and ions.

The different hardening effect on materials caused by the same amount of creep and plastic deformation can attribute to the difference between the substructures resulted from the different loading history.
