High heating current dependence of the IGBT module junction-case steady state thermal resistance is investigated. The conception of the thermal resistance and the physical structure of the IGBT module and the thermal impedance test principle are briefly introduced. The junction-case thermal resistance can be deduced by Finite Element Method in the numerical simulator ANSYS. The transient therma...

Thermal resistance is a key technical index which indicates the thermal management of multi-chip module high power LED (MCM-LED) packaging heat dissipation system. In this paper, the prototype structure of MCM-LED packaging heat dissipation system is proposed to study the reliable thermal resistance calculation method. In order to analyze the total thermal resistance of the MCM-LED packaging he...

Ohmic and Schottky contacts are playing a major role in the field of ZnO based electronics device fabrication. It is seen that several works have been reported on metallization scheme, contacts with this semiconducting material. But, the thickness of semiconducting material and the choosing of substrate still remain imperfect and inefficient for advanced IC technology. To estimate contact resis...

In modern information technology, as integration density increases rapidly and the dimension of materials reduces to nanoscale, interfacial thermal transport (ITT) has attracted widespread attention of scientists. This review introduces the latest theoretical development in ITT through one-dimensional (1D) atomic junction model to address the thermal transport across an interface. With full con...

The abrupt change in material properties across the interface between different materials can result in large inter-laminar stresses leading to delimitation, cracking, and other damage mechanisms which result from the abrupt change of the mechanical properties at the interface between the layers. Initially the uncertainty in material properties at micro level is finally reflected as macro level...

We report the thermal behavior of gadolinium foils to be used in magneto thermoelectric generator cells. Magneto thermoelectric generator cell technology exploits the ferromagnetic phase transition of gadolinium to drive the movement of a diaphragm ‘shuttle’ whose mechanical energy is converted to electrical form and which enhances heat transfer through both conduction and convection. Efficient...
