Supercompliant Lattice Boosts n‐type AgSbTe2 Thermoelectrics
Advanced Functional Materials, EarlyView.The supercompliant lattice design enables the first realization of n‐type electrical transport in AgSbTe2 by overcoming intrinsic electron‐killer defects and exceeding the doping limits imposed by the conventional Hume–Rothery rule. Accordingly, the best performance n‐type Ag0.8Na0.3Sb0.6Bi0.4Te2 sample achieves a low κ of 0.27 W·m−1·K−1 that ...

Package Hermeticity Testing with Thermal Transient Measurements [PDF]
Dans Symposium on Design, Test, Integration and Packaging of
MEMS/MOEMS - DTIP 2008, Nice : France (2008), 2008 The rapid incursion of new technologies such as MEMS and smart sensor device manufacturing requires new tailor-made packaging designs. In many applications these devices are exposed to humid environments. Since the penetration of moisture into the package may result in internal corrosion or shift of the operating parameters, the reliability testing of ...
