Sulle variazioni dell’ effetto peltier in un campo magnetico

Peltier cooling in molecular junctions.

The study of thermoelectricity in molecular junctions is of fundamental interest for the development of various technologies including cooling (refrigeration) and heat-to-electricity conversion 1-4 . Recent experimental progress in probing the thermopower (Seebeck effect) of molecular junctions 5-9 has enabled studies of the relationship between thermoelectricity and molecular structure 10,11 ....

Acknowledgements I would like to thank Prof. Paolo Massazza, my first algorithm professor, for the supervision of the final drafting of the thesis and his precious suggestions; I also would like to express my gratitude to Prof. Jyrki Katajainen, coau-thor of the two articles presented in the thesis, for what he taught me, his constant encouragements and all the time he dedicated to our collabor...

Bias-dependent Peltier Coefficient in Bipolar Devices

Temperature stabilization is important in many microelectronic devices due to thermal constraints on device operation and lifetime. The work described here is an investigation of thermoelectric phenomena in bipolar devices, speci£cally the p-n diode. Current injection can modify the Peltier coef£cient at interfaces; this can give rise to thermoelectric cooling or heating depending on device par...

Wiki e Matematica: costruzione di competenze

L’organizzazione di un wiki web a scuola può fornire l’opportunità per un miglioramento delle competenze disciplinari. In questa esperienza la metodologia del learning by doing trova una piena applicazione e diventa spunto di riflessione sui problemi che si incontrano nell’istruire all’uso delle nuove tecnologie e sulla necessità di educare ai corretti comportamenti all’interno dei social netwo...
